Comment (by enolan):

 It works before the commit and doesn't after. It may be fair to blame API
 Monitor's developer, but the exception handlers are definitely involved.
 Maybe API Monitor method of hooking triggers the exception handler and
 it's incorrectly interpreted as a segfault? You definitely know more about
 this than me.
