EEschema crash when I hit ERC button

I cannot duplicate this. If possible, please include a minimal schematic that causes the problem. I've tested most of my schematics and most of the kicad demo schematics without an issue.

I tested demo projects in "KiCad\share\kicad\demos" with BZR 6154

* complex_hierarchy
* flat_hierarchy
* electric
* kit-dev-coldfire-xilinx_5213
* pic_programmer

all crash.

And I came from this post.
https://forum.kicad.info/t/drc-in-eeschema-bzr-6115-6127-crashes/1221

Can I dump something from the crash?
I attached the screenshot when program crash.

I 'm the original poster from
https://forum.kicad.info/t/drc-in-eeschema-bzr-6115-6127-crashes/1221
the problem occurs in all schematics, even an empty one from a new project
When I draw a small schematic and hit the middle empty button in the ERC windows, ERC seems to work.
when I hit refresh in the ERC settings window even the 3 empty buttons disappear ( see ERCproblem2.jpg).
I asked a friend to check this on his PC. he installed a recent KICAD version, and eeschema even crashed, when starting ERC.
Both machines Win7 64bit KICAD 32 bit

PS: Thank you developers for KICAD, the best freeware EE design software ever !

I cannot duplicate this issue (W7, 32 bits).

It look like a build issue, or some incompatible library.

Have you built Kicad yourself on you computer?
If no, where is the source of these binaries?

I download them from

http://downloads.kicad-pcb.org/windows/

and old versions from

http://www2.futureware.at/~nickoe/

I have tried several versions and I think there must be some code difference lead to this problem, because ERC are working on old versions I tested:

kicad-product-r5528.036404d-i686.exe
kicad-product-r5989.9b9c794-i686.exe

I perform uninstall and then check the kicad folder is deleted each time I try. So I think the enviroment on my PC is the same for old and latest versions.

I am trying to build the debug versin of KiCad using "kicad-winbuilder-3.4" now. I will tell you guys if I find something usefull.

I can confirm the snapshot from http://downloads.kicad-pcb.org/windows/ does not work on my computer (W7 32 bits).
Here is something wrong in a library.

I did exactly the same lichee did, exept that I don't want to install and manage the build chain :-)
error still there in r6171 (GIT1869401)
how could I help to get rid of this problem ?

You mean BZR 6167 Git 168940, BZR 6171is in the future at the current time.

@Jean-Pierre, can you provide more information about the issue with the library?

I am on this issue.

On Windows 7 32 bits, I have 2 build chains (both using wxWidgets 3.0.2).
- if I build Kicad with the latest "native" msys2 install (with gcc 5.2.0) I have this issue.
- If I build Kicad with a previous msys2 install (with gcc 5.2.0) 4.9.2 and wxWidgets build by myself (my usual build chain), all works fine.

- Winbuilder build also works fine.

There is the reason I am thinking there is a build/library issue, but I did not find exactly the reason.
(Built a full kicad version + a full wxWidgets version is very time consuming)

I cannot try the 64 bits build version.

Ok, nice to hear Jean-Pierre. I was trying to debug it yesterday but all I found was that it did not crash on the 64-bit build. But they were not really testing the same revision, but now the new nighties have a 32- and 64-bit build of the same revision. The compiler version should be the same, but I can try to verify that later.

Just installed BZR 6170 from http://downloads.kicad-pcb.org/windows/ both 32- and 64-bit version : can confirm ERC in 64-bit version ok; 32-bit: problem still there

Gcc 5.2.0 and wx 3.0.2 is used for both builds on the build server FWIW.

Can you try rev 6177 ?

Problem solved ! The BZR 6177 version which I download from

http://downloads.kicad-pcb.org/windows/

do not crash on ERC.

Thanks to all your work.

PS1: My build debug version kicad work has failed many times on linking some pcbnew modules , and I tried 2 times from a fresh new start, servel times with pcbnew folder deleted in debug folder. At last I give up on this.

PS2: I am doing placement until now on my PCB Project on KiCad, I have to say it is intuitive to use, before that I remember when I learn PADS, I even read the manual to find how to use mouse in layout interface.

@lichee, thank your for testing. I will mark this as fixed then.

great, thanks a lot for fixing it!
