Comment 1 Ben Beasley 2022-01-14 19:28:07 UTC

This is breaking sleef on ppc64le, too.

Comment 2 Ben Beasley 2022-01-14 19:29:45 UTC

To be clear, this appears to be a GCC 12 regression.

Comment 3 Jakub Jelinek 2022-01-14 20:30:44 UTC

I'll start a fixed gcc build tomorrow morning UTC, still waiting for some other fixes to be tested.

Comment 4 Ben Beasley 2022-01-14 20:37:11 UTC

Thanks!
