The will_not_call_mercury in that test case is a lie - the pragma c_code
exits using a tailcall() and a proceed(), rather than falling through. If the
C code is marked may_call_mercury, a stack frame is created to save the
succip, but the stack frame is not removed on exit. The result is that
the stuff after the call to the C code is executed multiple times.

Zoltan is coming up with a slightly cleaner test case.
