--- Comment #2 from janus at gcc dot gnu.org --- (In reply to Richard Biener from comment #1) > Would be nice to know what fixed this (or maybe know if it just went latent). I think I remember having some intermediate versions during the reduction that failed also with 8 and trunk. So I'd guess it just went dormant, or the segfault depends on memory layout or something. Wanted to try valgrind on the exe, but it seems it doesn't support AVX-512 yet (at least the version I have).
