When I try to build the firefox 92.0-1 package with an unodified PKGBUILD in a clean chroot (using extra-x86_64-build from the devtools package and an unmodified /usr/share/devtools/makepkg-x86_64.conf from the same package), I keep getting the following error:

I've attached logfiles of the entire package compile run, produced by running

extra-x86_64-build -c -r /mnt/archbuild > >(ts '%F_%H:%M:%S' | tee -a stdout.log) 2> >(ts '%F_%H:%M:%S' | tee -a stderr.log >&2)

I've had the exact same issue when trying to build Thunderbird 91.x for a few weeks now, even though building thunderbird 91.0.2 on 2021-08-23T13:05:06 CEST worked without issues. I've suspected LTO, but neither adding "!lto" not "lto" nor omitting it from the options array in the PKGBUILD resolved the issue.
This task depends upon

Does the journal show SIGKILL was sent by the kernel OOM killer? If so try reducing the number of jobs with mk_add_options MOZ_MAKE_FLAGS="-j#"

Ohhh, thanks for the hint, journalctl shows OOM kills of some rustc processes indeed, and /mnt/archbuild is a tmpfs, which obviously isn't helpful in an OOM situation. I'll report back if this actually solves the issue.

After throwing zram and a swap partition the size of Texas at the problem, the build process finally worked without any issues. Reducing the number of make processes didn't help since the bottleneck/memory hog seems to be a single rustc process.

Thanks again for the hint, loqs! 👍
