Is that the exact script used? I ask because if you have functions, you 
will get an execution hook for each function declaration in the 
top-level script as that is run (even if there's no code outside functions).

If it is the exact script used, can you try dumping all the PC values 
through a single run? I'm interested in whether the places it stops on 
line 1 and 7 are PC values that it hits again during the 'real' run.
