I think it is in fact expected that dynamic formats (as well as external
mode) are crashable (and more) with certain configuration file settings.
However, I think it may be practical to make reasonably defined dynamic
formats not crashable with bad password files (even with purposefully
malicious ones).
Do you agree? What's the current state of dynamic formats with respect
to bad password files?
