Eclipse SIGSEGVs in libpango

known problem with packages provided from eclipse.org. please use the one from the distribution (karmic)

Same problem, but slightly different software:

Eclipse is installed manually but up-to-date (3.5.1)

JRE version: 6.0_16-b01
# Java VM: Java HotSpot(TM) Client VM (14.2-b01 mixed mode, sharing linux-x86 )
(from package sun-java6-bin, version 6-16-0ubuntu1.9.04)

My question: WHY do i have to use eclipse from the distribution? There is nothing special to eclipse - it could also be every other SWT application...

libpango1.0-0, Version: 1.26.0-1

Also see strange behaviour when clicking buttons. Mostly they feel like i did not release the mouse button and then i have to press RETURN to start the action...

I also experience that button behaviour, but I think this is not related. Would you mind to create a bug report for that?

"it could also be every other SWT application" - ACK. If Eclipse is able to crash the JVM, every Java program could, right?

@nh2:
I see, you use openjdk 6. i use sun-java6-bin. and my eclipse is manually installed, so it uses only the standard dependencies from ubuntu. which package should I assign such a bug to?
I also see that eclipse process does not terminate anymore, but the all its windows and the profile lock were close correctly. system monitor tells futex_wait_queue_me.

And yes: I dont have any SWT testing application to check but i think it is a general problem.

@Daniel:
You should create one bug for each problem (I see the futex_wait_queue_me, too) and assign it to the Eclipse package - if somebody knows that it belongs to another package, he will just change it.

By the way, I have these bugs with both OpenJDK and Sun's Java.

@nh2:
I see there are already bug reports, and workarounds for both too:
Termination: Bug #293849 & Bug #299828
Buttons: Bug #443004

Confirm. I have installed eclipse from repo. And it's not working with both OpenJDK and Sun's Java.

the vm crash report in comment #8 seems to be incomplete

% opt/eclipse3.5/eclipse

you should report this problem where you got this version

@ Matthias:
It's the current "Eclipse IDE for Java Developers" available on eclipse.org.
I've filed the bug against OpenJDK because I do not know how a Java program can crash its JVM - why could that happen?

native code as distributed by eclipse.org, especially swt-gtk, xul and the like.

I found a upstream bug in https://bugs.eclipse.org/bugs/show_bug.cgi?id=291128

This happens with Karmic's Eclipse package, too.

To reproduce:
sudo apt-get install eclipse
eclipse
Click Help -> Install new Software -> Cancel -> You get the SIGSEGV

This happens with Karmic 64bits too.
I've tried everything:
-Ubuntu's Eclipse package
-Install manually Eclipse
-Delete ~/.eclipse

And it's just like #15

(Un)Fortunately, this does not happen on every system.
My Karmic Netbook sigsegvs while my Karmic Desktop does not.

Does your netbook have intel video? I have this problem on my HP 530
laptop. Can someone try it on non-intel video environment, please?

This appen to me too.

I'm running sun jdk from karmik repo, ati radeon 3200, intel core 2 (sony notebook).

Eclipse crashes everytime i click a "cancel".

So you if you want to reproduce this, just: File -> Import -> click cancel.

And you'll get this:

# SIGSEGV (0xb) at pc=0x002bd856, pid=4776, tid=3078371008

We found a workaround in Bug 460104.
Click System -> Preferences -> Assistive Technologies -> Untick first checkbox and re-login, Eclipse should work now.

Confirming that disabling Assistive Technologies prevents the pango crash. However, I still have the button interaction issue where I need to use the keyboard to press a button.

@Arlo:

isn't it bug 442078 ?

it should already be fixed in the repository version...

as a workaround for my old manual eclipse install i created a shell script with this line:

export GDK_NATIVE_WINDOWS=true && ./eclipse

thanks nh2 and Dario Bertini
Eclipse Galileo ( and 3.6XX) is working properly in Ubuntu 9.10 32bit after these tips :)

I don't have Assistive technologies in my Preferences, does anyone know how to get it?

Open (in a terminal or alt+f2) gnome-at-properties

Thanks, I also found:
$ gnome-control-panel

and then you can select and turn it off.

turning off assistive technologies did not help me, eclipse (galileo SR1 from eclipse.org, not from repos) was still crashing when trying svn checkout (tigris.org subclipse plugin). The cure was as follows:
remove/rename libcairo-swt.so in eclipse folder to something that is not recognized as shared library, for example libcairo-swt.notsoso
apt-get install libswt-gtk-3.5-jni (i have karmic-proposed repos enabled so i got 3.5.1+repack~1-0ubuntu3 but it might work with earlier versions as well)
run eclipse and code away

apparently it did let me run checkout only once, now it crashes again :(

Can not confirm the workaround in #27 worked for me.
@Raivis: Did you restart your session after disabling assistive technologies?

The packages for Eclipse Galileo that are in Ubuntu's repositories (3.5.1+repack~1-0ubuntu1) do crash in Ubuntu, but do run in Kubuntu.

An example (that is not the only way of making Eclipse crash in Ubuntu in this way):

On Kubuntu:

Install Eclipse with K package manager or whatever.
Launch Eclipse
Click "Help" - "Install new software"
Setup Galileo repo
Select section "Programming Languages"
Select "Eclipse C/C++ Development Tools"
Click "Next" (Eclipse calculates dependencies, then shows you the packages you are going to install)
Click "Finish" (Eclipse downloads and installs CDT).

On Ubuntu:

Install Eclipse with Synaptic.
Launch Eclipse
Click "Help" - "Install new software"
Setup Galileo repo
Select section "Programming Languages"
Select "Eclipse C/C++ Development Tools"
Click "Next" (Eclipse calculates dependencies, then shows you the packages you are going to install)
Click "Finish" (Eclipse crashes and disappears).

If on Ubuntu Eclipse was launched from a console, at the moment it crashes you get this console output:

Pixie dust recipes that did not work:

* Install clean download from eclipse.org (same behavior)
* setting GDK_NATIVE_WINDOWS=1 before launching Ubuntu repo or eclipse.org version (same behavior)

I insist: It DOES work OK in Kubuntu.

uhm, very interesting!

Does Kubuntu have "assistive technologies" ?

Oh, I had missed the bit about relogging after disabling assistive technologies. I hereby confirm that disabling assistive technologies and relogging did make Eclipse work.

It is funny that it works out of the under Kubuntu, when it calls GTK just the same. I imagine GTK under Gnome does use Gnome libraries, and not only the other way around.

I can not turn off assistive tecnologies because I am blind and need to use eclipse with orca.
For while I'm using eclipse with windows. A solution would be welcome.
Thanks.

Now I cannot do checkout using Subversive plug-in. Turning "Assistive
Technologies" off does not help any more.

@ Oleksandr:
Could you tell us steps to reproduce?

To reproduce try the following steps:
1. Download and install eclipse 3.5.1 from http://www.eclipse.org
2. execute eclipse.
3. Press alt+h and chose install software.
4. press the cancel button.

Hi I use the GDK_NATIVE_WINDOWS but it does not resolve the issue for me.

When I do an SVN update or commit, the eclipse GUI freeze and become blue with no interaction possible. It happen no every times but 50% of the times.

I think it is due to credential dialog but I'm not sure of this.

Anyone has my same issue?

@ Jose: This is clear to me, but it seems that Oleksandr's Eclipse crashes only on Subversive checkouts and not on the original bug on cancel buttons.
@ Oleksandr: Is this right?

Hi, I solved my bug on #37 by use SvnKit instead of javaHL.

Another steps to reproduce:
1) Run Eclipse
2) Go to "Window -> Preferences -> General -> Keys"
3) Click on "Cancel" - Eclipse crashes
Disabling gnome assistive technologies helped me.

Used SW:
Ubuntu 9.10, amd64
Eclipse 3.5.1
