--- Comment #4 from Sergei Trofimovich <slyfox at gcc dot gnu.org> ---
I suspect a similar regression on python-3.12.7. Bisected to the same `gcc`
commit.
The reproducer:
# build gcc
$ ~/dev/git/gcc/configure --disable-multilib --disable-bootstrap
--disable-lto --disable-libsanitizer --disable-libstdcxx-pch
--enable-languages=c,c++ --disable-libgomp --disable-libquadmath
--disable-libvtv 'CFLAGS=-O1 -g0' 'CXXFLAGS=-O1 -g0' 'LDFLAGS=-O1 -g0'
--prefix=/tmp/gb/__i__
$ make -j$(nproc)
$ make install -j$(nproc)
# build python
$ wget https://www.python.org/ftp/python/3.12.7/Python-3.12.7.tar.xz
$ tar xf Python-3.12.7.tar.xz
$ cd Python-3.12.7
$ ./configure CC=$PWD/../__i__/bin/gcc CXX=$PWD/../__i__/bin/g++
$ make
./_bootstrap_python ./Programs/_freeze_module.py abc ./Lib/abc.py
Python/frozen_modules/abc.h
Fatal Python error: _PyImport_InitCore: failed to initialize importlib
