Comment 4 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-12-26 10:43:45 UTC 
gtest shell_cmds has 'free(): invalid pointer' at the end, I don't immediately see where dos_files crashes tho.

Adding to gcc-15 tracker just in case it's related.
Comment 5 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2024-12-28 14:34:32 UTC 
ago, can you hit it with gcc 14?
Comment 6 Agostino Sarubbo gentoo-dev 2025-01-03 20:24:51 UTC 
(In reply to Sam James from comment #5)

Comment 11 Sam James archtester Gentoo Infrastructure gentoo-dev Security 2025-01-14 11:49:59 UTC 
I get another crash if I build with -Og at teardown. The test also passes if I run just that one test with --gtest_filter, it seems.

I'll bisect GCC first as it's useful info either way.
