Looking for a better solution I had a look at
- CPAN issue tracker
- Fedora patches
- other distribution patches
- the github fork of Wx-Perl (see #1090963)
but didn't find a better solution than the workaround with the
temporarily disabled optimization.

I was able to reproduce the issue with the github fork, which is
actively maintained, so I reported the issue there:
https://github.com/sciurius/wxPerl/issues/10

I cross-checked everything in an amd64 sid chroot and the problem can
be fixed by using gcc-15 (instead of gcc-16) or by applying Nikos
workaround patch.
