     PATCH: [perl #133889] Assertion failure
     
     I did not bisect this, but this is a regression.
     
     This code is using a user-defined property that isn't defined.  It
     should catch that and, since this is within regex sets,  quit, but
     instead continues and ends up using an undefined value.
