--- Comment #9 from Chris Elrod <elrodc at gmail dot com> --- > Interestingly this seems to be only reproducible on Arch Linux. Other gcc > 13.1.1 builds, Fedora for instance, seem to behave correctly. I haven't tried that reproducer on Fedora with gcc 13.2.1, which could have regressed since 13.1.1. However, the dup example in https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114276 does reproduce on Fedora with gcc-13.2.1 once you add extra compile flags `-std=c++23 -fstack-protector-strong`. I'll try the original reproducer later, it may be the case that adding/removing these flags fuzzes the alignment.
