--- Comment #1 from Stefan Krah <stefan at bytereef dot org> ---

The issue can still be reproduced with a gcc-14 snapshot. ibm-clang++ does =
not

Would it be possible for gcc to use the LLVM libunwind on AIX? It would be
great if IBM unlocked some funding for this.

gcc issue on AIX that I've come across after many long running tests. It wo=
uld
be worth fixing --- both AIX and gcc (except for this issue) are very stabl=
