Excuse the poor testcase but i was just trying to get the feel of gomp on non
trivial code.
It looks like some memory corruption (from the look of the nuked stack), the
bigger the better.
[time passes] It seems that if i leave exceptions on, an assert is hit. Here's
how it looks with that minimal option set. Backtrace included.
