Is it reproducible?

Could you follow ttps://wiki.gentoo.org/wiki/Gcc-ICE-reporting-guide together?

[Comment 2 Sam James 2022-06-02 03:34:03 UTC]

Could be related to https://gcc.gnu.org/bugzilla//show_bug.cgi?id=104637.

It's unfortunately reproducible :-)

I'll follow the ICE reporting guide and provide the extra information.

Preprocessed source file

Compiler command line to reproduce the issue:

LANG=C /usr/bin/x86_64-pc-linux-gnu-g++-11.3.0 -O2 -march=skylake -std=c++14 -o CGBuiltin.cpp.o -c CGBuiltin.cpp.ii

[Comment 5 Laurent Pinchart 2022-06-06 09:07:44 UTC]

I've compiled the preprocessed source with gcc 12.1.0, and the ICE is gone. It would still be nice to get the fix backported to gcc 11 though, especially given that gcc 12 isn't stable on amd64 yet.

[Comment 6 tt_1 2022-06-21 05:45:18 UTC]

upstream patches for this were backported to gcc-10/11 branch

[Comment 7 Sam James 2022-06-21 06:02:33 UTC]

Thanks both. I've been wondering what to do here, given I'm likely to keyword GCC 12 this week if the 0ad ICE bug gets fixed (and I hope it will: bug 847601).

My very provisional plan is to push a fixed 11.3.0 (this patch, maybe one or two others, or just keyword one of the snapshots) at the same time as 12.x so that only folks who have 12 masked (fairly common to do for major versions) have to build it, rather than doing e.g. fixed 11.3.0 today in ~arch, then in a few days everyone in ~arch has to build 12.1.0_p*.

[Comment 8 Sam James 2022-06-26 04:34:16 UTC]

12.1.1_p20220625 now keyworded. Bit tired out from the work for that but I'll get around to backporting the 11 patch soon.
