Created attachment 887557 [details] patch to reproduce issue easily This patch makes it easier to reproduce this issue since then emacs will fail emerging without -flto.
It's always worth giving full context, e.g. the discussions you and I had on the libgccjit ML. Anyway, if GCC is ICEing, then it's something to report to the GCC bugzilla (if you have a standalone test case), or bring it up on the libgccjit ML and ask for advice.
True. This is the original thread I started on the libgccjit mailing list: https://gcc.gnu.org/pipermail/jit/2024q1/001853.html Basically, this started as an issue with libgccjit not being compiled with LTO support but that was fixed. I also started a thread in emacs-devel but no one there is able to reproduce it and they suggest reporting it to Gentoo: https://debbugs.gnu.org/cgi/bugreport.cgi?bug=69689
What package provides libgccjit.so?
You need to report it to the libgccjit people. It's not an Emacs bug for it to ICE (although it's possible that the libgccjit integration in Emacs needs to do something to enable compression).

Pass down the zstd arg from USE=zstd like we do for the regular build. Thanks to StrawberryTea for reporting.
