There's no reason to ignore execute access errors, those are bugs
too. You are still not filtering the exception properly though, the
condition checking has to be done directly in the handler, you can't
longjmp back to the code and then re-raise the exception. That's doubly
true for the finally handling. This means you have to generate different
handlers for the different exception conditions.
