For certain ops, the old CFF code was more tolerant of poor "stack management" in certain ops, in this case: VVCURVETO, HHCURVETO, VHCURVETO and HVCURVETO. Basically, if an inappropriate number of parameters were pushed on the stack, those ops would "round down" to the next nearest valid value, and ignore the remains.

Patch attached adds the same tolerance to the new code.
