On a c7a.large instance (EPYC 4th generation), the first one exits with
exit status 0, but then: "mlucas -s m" segfaults, and creates a core
which I've just put here in case it helps:
https://people.debian.org/~sanvila/build-logs/mlucas/core.gz
(gdb says "Core was generated by `/usr/libexec/mlucas/mlucas-avx512 -s m'")
(Beware: It's 956 MB big when uncompressed).
I get a 403 error, I suppose you need to use chmod.
Oops! Sorry, yes, I've fixed the wrong permissions now.

Before I do that, could you check that
/usr/libexec/mlucas/mlucas-avx2
actually pass the test-suite on epyc 4, just to be sure ?
Yes, I confirm that the package builds ok (including the tests)
when I apply the attached patch.
Thanks.
