Before the invocation of the profiling routines, no successors is correct.
During the invocation of the profiling routines, however, we add fake 
edges from calls to the exit block.  I would not expect this to change
for a noreturn function like longjmp.

So I guess the quesion is "where did you get this null, exactly?"
