--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
stack size              (kbytes, -s) 65532
is 64M, that should be more than enough.  Of course unless darwin
pthread_create does something dumb, like using far smaller stack sizes for
threads by default.
In that case, the question is if we shouldn't override that on darwin to
something larger, or just use
! { dg-set-target-env-var OMP_STACKSIZE "8M" }
on the test.  Note that dg-set-target-env-var doesn't (yet?) support target
specification as 3rd argument, so I'd prefer not to add that.
Or we could add -finline-matmul-limit=64 or whatever works.
