test failures

4.0.0 as well as 4.0.1rc1 fail several OpenMP-related tests with a stack trace.
trunk/master HEAD passes all tests, so it seems it's just a matter of
backporting the right commit(s), but I couldn't find an obvious suspect from a
cursory look. I'm sure somebody else will know what's causing this from a quick
glance.

Shortened test log is attached

What platform is this? Self-hosting on a Mac or built with something else?
