--- Comment #12 from Andrei Alexandrescu <[email protected]> ---
We've just had this issue at work, looks like undefined behavior. An
associative array with keys deleted during iteration caused crashes without
stack trace and without core dump.

The right thing here is to throw an exception if an AA is removed from during
an iteration.
