Your encoder is producing something invalid, or some memory corruption
is happening. What 264parse does is perfectly correct. Here's what the
spec says:

   7.4.2.2
   Picture parameter set RBSP semantics
   pic_parameter_set_id identifies the picture parameter set that is
   referred to in the slice header. The value of
   pic_parameter_set_id shall be in the range of 0 to 255, inclusive.
