A known issue: the flow space doesn't consider that almost any operation
could raise MemoryError, and thus the except clause is never seen by it.
The same issue applies to try:finally:.

The workaround is to use a function call:

    def fn():
        except MemoryError:
            return True
            return False

    def do_stuff():

A bientot,
