Thanks for the report. But I'm unable to reproduce the issue. I'm testing on a
Skylake-AVX512 system. I even did a clean rebuild of all of GCC using your
configuration (minus your prefix) and still no failure.
Could you please send me your libstdc++.log after failing the test?
Best,
Matthias

Thank you. Since you only executed one test it's not that bad (it's hard to
read without a few abbreviation substitutions).
Anyway, it

Hi,
I looked into this and still don't understand how to reproduce it.
The issue as logged in libstdc++.log is a call from
find_last_set(simd_mask>) to
_MaskImplNeonMixin::_S_to_bits, which calls vpadd_s32 with two
[[gnu::vector_size(8)]] int arguments. The CI compiler complains "error:
