First reported upstream in: https://github.com/openzfs/zfs/issues/13620 It didn't happen before (with the same cflags), I suspect it's either gcc (upgraded from 11 to 12.1.1_p20220625 recently), or zfs itself. I normally have CFLAGS="-O2 -march=native -pipe -ggdb", native should be equivalent to znver2 for me. Removing the -march fixed it, so perhaps we should force that in the ebuild until it's fixed upstream. Reproducible: Always

Segfault occurs w/ 'zfs send' otherwise (and very possibly other commands). Let's backport for older versions to be safe after discussion w/ gyakovlev.
