It might help to remind that you can't run anything using the regex engine while you're inside a (?{...}) or (??{...}) block. You'll usually get segfaults and such if you do that. The engine isn't re-entrant and if you invoke a regex during a regex, you scribble on memory. Its supposed to have gotten better during 5.8 but I haven't tried it again.
