--- Comment #6 from seurer at gcc dot gnu.org --- The stack limit test case mostly has worked since just after this was opened (one short span where it failed again) but I don't know what fixed it. The other test case has worked fine since just after this was opened. Hopefully bootstrap on s390 hasn't been broken since June!
