Tobias Schlüter <tobi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Attachment #48779|0 |1 is obsolete| | --- Comment #8 from Tobias Schlüter <tobi at gcc dot gnu.org> --- Created attachment 48927 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=48927&action=edit Reduced testcase (32bit, preprocessed). I've further reduced the testcase down to 800Kb. Again this is with -m32. I removed the definition of void Eigen::internal::check_for_aliasing, so this will appear in the assembly, but it's a no-op. New version attached, compiler explorer version here https://godbolt.org/z/h6YMeq I've also reproduced the bug with 10.2
