--- Comment #7 from Richard Biener <rguenth at gcc dot gnu.org> --- Created attachment 36993 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=36993&action=edit candidate patch Can you try if the fix for PR68852 (attached) fixes this? If not, can you attach -fdump-tree-slp-details (two dump files) before and after the rev. for that file?
