gdb context and complete backtrace
Culprit code is actually in media-libs/exempi. In fact they have aligned/unaligned routines, but the aligned ones are gated behind a check for Solaris, rather than a generic sparc check.
This is wrong as unaligned access is UB on all platforms.

Have opened an upstream PR to fix this https://gitlab.freedesktop.org/libopenraw/exempi/-/merge_requests/8 Will dekeyword it. The bug has been referenced in the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=42c8de509fad0101dec2446d51000bcc9d1ba6c1 commit 42c8de509fad0101dec2446d51000bcc9d1ba6c1 Author: Michał Górny <mgorny@gentoo.org> AuthorDate: 2024-06-05 16:10:19 +0000 Commit: Michał Górny <mgorny@gentoo.org> CommitDate: 2024-06-05 16:10:46 +0000 media-libs/exempi: Dekeyword on big endian arches Remove keywords for big endian architectures, the package is broken on big endian architectures according to upstream. We did not notice this before because of insufficient test coverage.
