> Interestingly this seems to be only reproducible on Arch Linux. Other gcc=

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=3D=
114276
does reproduce on Fedora with gcc-13.2.1 once you add extra compile flags
`-std=3Dc++23 -fstack-protector-strong`.
I'll try the original reproducer later, it may be the case that adding/remo=
ving
these flags fuzzes the alignment.=
