Yeah!

I run into the same thing with a 16C63. After returning from the call or
goto the PCLATH register remained unchanged, so when another jump or branch
was found the thing would jump crazy.

I thought at first that I misunderstood the datasheet, but now I see that I
am not the only one. If they meant something different I think they
(Microchip) should clarify it.
