Embedded?  The PDF file you refer to doesn't contain a single embedded
font...

I think this is not the right fix – regardless of the hinting engine,
a CFF must not be malformed.  However, the constant `3' is probably
wrong.  Please try this line instead:

  if ( ( ip + 1 + ( ( decoder->num_hints + 7 ) >> 3 ) ) >= limit )
