     PATCH: [perl #133937] Assertion failure
     This recently added assertion actually caught an error, which is a
     potential read beyond end of buffer.  This doesn't actually happen in
     this case because this is a regular expression pattern, and the toker
     makes sure there is a trailing NUL (that isn't counted).
     The solution is to check the bounds before reading.
