Bug Description

The build hangs forever when compiling the webrender rust crate (see https://launchpad.net/ubuntu/+source/thunderbird/1:78.9.0+build2-0ubuntu3/+build/21368163). I'm attaching the full build log for future reference.

This happens when building with rustc 1.50.0+dfsg1+llvm-0ubuntu4 and 1.50.0+dfsg1+llvm-0ubuntu5 (the latter is the version currently in the hirsute release pocket).
The build completes when building with rustc 1.50.0+dfsg1+llvm-0ubuntu2.

Note that it's not just thunderbird 1:78.9.0+build2-0ubuntu3 in hirsute-proposed that is affected, rebuilding version 1:78.8.1+build1-0ubuntu1 in the release pocket hangs similarly.

FWIW, this happens in Debian as well; cf: https://ci.debian.net/packages/t/thunderbird/unstable/ppc64el/.

According to https://buildd.debian.org/status/logs.php?pkg=thunderbird&arch=ppc64el&suite=sid, Debian is not affected by the same build failure.

Gee, I wonder what's up with ci.d.net; it's basically dead for ppc64el for thunderbird. I'll try to take a look at this on the Debian side when I have some time.

I am now seeing similar build failures (where the build hangs forever before eventually being killed) when building the firefox 89.0 release candidate, on pcc64el, on bionic and focal (the version of rustc is 1.47.0+dfsg1+llvm-1ubuntu1. Groovy, hirsute and impish are not affected. I need to look into it further to understand if the hang also happens when building the webrender crate.

The firefox build failures are a different issue: bug #1930315.

Worked around the hang when building thunderbird by reducing the rust optimization level (from 2 to 1) when building on ppc64el: https://bazaar.launchpad.net/~mozillateam/thunderbird/thunderbird.impish/revision/623.

This is awesome! Would you mind submitting to Debian as well? I can probably re-trigger the builds there to get this working and we can drop the delta at some point.

As I wrote in comment #8, I'm not seeing that Debian is affected by this bug, it is an Ubuntu-specific toolchain issue.

Also, thunderbird in Debian and thunderbird in Ubuntu are (for historical reasons) entirely separate packages (see bug #1894090).

Aaah, I see. It looks like another problem then. Gotcha! Thanks!
