Thanks, That one's interesting, I'm actually a little surprised we don't see it anywhere in the test suite (it would seem any try/finally w/ a return should hit it, maybe those just aren't very frequent).  I've opened bug 872 for this.

Subject: [IronPython] NPE inside IronPython.Compiler

Following code, reduced from MoinMoin.util.lock, causes NPE inside IronPython.Compiler.

MoinMoin (http://moinmoin.wikiwikiweb.de/) is a popular wiki engine written in Python.

# lock.py
class WriteLock:
    def acquire(self):
            result = self.lock.acquire()
            if result:
                return result
