--- Comment #21 from Sam James <sjames at gcc dot gnu.org> ---
It fell out when building media-libs/flac's tests after I threw in -fipa-pta in
a test container for a single run where I check trunk for regressions.
Building flac itself, I can reproduce it with:
```
export CFLAGS="-O3 -ggdb3 -march=znver2 -fipa-pta -fno-vect-cost-model"
export CXXFLAGS="-O3 -ggdb3 -march=znver2 -fipa-pta -fno-vect-cost-model"
export LDFLAGS="-Wl,-O1"
cmake -B build-bad -DINSTALL_MANPAGES=OFF -DCMAKE_BUILD_TYPE=Debug
-DBUILD_SHARED_LIBS=ON
make -C build-bad
ctest --test-dir build-bad -R generate_streams
ctest --test-dir build-bad --tests-information -o -R replaygain
--output-on-failure
```
(*BUILD_TYPE and *SHARED_LIBS can be emitted if desired - was just there for
debugging while I went as wanted assertions, and you can just run make -C
build-bad and then make -C build-bad check).
It fails like:
```
[...]
