dev-vcs/subversion-1.14.5 segfaults when checking out a project, building with `-mavx -O3 -pipe` seems to be enough to make it crash.

Do any svn tests fail?
(In reply to Sam James from comment #2) > Do any svn tests fail? Only io-test fails, but that fails with just CFLAGS="-O2 -pipe" too, and there is already a bug for it - 938103, where gcc 14 is used, so it's entirely unrelated.
ACK, thanks.
