Thanks; I guess I misunderstood the semantics of computed gotos. On closer
inspection of the GCC manual,
"You may not use this mechanism to jump to code in a different function.
If you do that, totally unpredictable things will happen. The best way
to avoid this is to store the label address only in automatic variables
and never pass it as an argument."

computed goto's can only goto local labels or gotos in the contained functions.
I don't see the bug here really.
