https://github.com/dovecot/core/commit/992a1726a41b42fa47204565ff17f7c635fcb421#diff-2ab6702cfaece1b12667261b923fd6aa9825371473736cfdd27c8db41c38d658R36 The test is bogus, I think. t_malloc is marked with __attribute__((malloc)) so its result is assumed not to alias anything, so a == b has to be false. It started with r15-580-gf3e5f4c58591f5 in GCC 15.
The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=3f6ee19d3cd09c9013d194536215efcbae04c057 commit 3f6ee19d3cd09c9013d194536215efcbae04c057 Author: Sam James <sam@gentoo.org> AuthorDate: 2024-12-28 13:44:04 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2024-12-28 13:47:06 +0000 net-mail/dovecot: test fixes, hardening tweak * Fix tests with GCC 15 (upstream PR#229, bug #939857). The test had a bogus assertion which was exposed by GCC 15. * Fix tests with LTO (upstream PR#230). I was convinced that I'd backported these fixes already but apparently not. This one fixes a real problem where dovecot would be miscompiled because of strict aliasing violations in the md4+md5 code. Thanks to parona for the help with (re-)testing it and confirming the fixes. * Pass --disable-hardening because it just copies the defaults even on vanilla profiles these days. For hardened, it actually makes things less safe because it does -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 which overrides the default of -D_FORTIFY_SOURCE=3 there.
