Running this test bus errors.
Per leo, this is because a failed compilation is returning a NULL
PMC, but isn't signaled as an exception.
Test may need to be fixed up once this does throw an exception. And
add a new test to insure we don't bus error on invoking something we
shouldn't.
Here's the gdb bt:
