The Red Hat folk are seeing a problem with that combination:
https://bugzilla.redhat.com/show_bug.cgi?id=1940964
which boils down to
> Build fails with this error:
> ERROR: failed to JIT module: Added modules have incompatible data layouts:
E-m:e-i1:8:16-i8:8:16-i64:64-f128:64-a:8:16-n32:64(module) vs
E-m:e-i1:8:16-i8:8:16-i64:64-f128:64-v128:64-a:8:16-n32:64(jit)
(By "build", I imagine the reporter means "regression tests")
So I was wondering if we'd tested it yet.
