That grade does not make sense. Minimal model tabling works by
doing surgery on the execution stacks, saving and restoring stack segments.
If another thread is executing at the same time, it is guaranteed
to have its stack accesses screwed up by this.
There is a compiler bug here, but the bug is that the compiler
even tried to generate code for this combination, instead of
printing an error message.
