--- Comment #1 from Sam James <sam at gentoo dot org> ---
[If you want to reproduce this from scratch with Python 3.12: (export
CFLAGS_NODIST="-O2 -fwrapv -mcpu=powerpc" ; ./configure --enable-shared && make
-j$(nproc) CPPFLAGS= CFLAGS= LDFLAGS= ) should do it, but that's not necessary
here.]
Reproducer tarball with ppc32 object files and a `reprod.sh` script (as well as
already-broken libpython3.12.so + `python` binary):

Access is possible to the machine (it's a clean test env) if needed.
