Mnemonic   Description         EquivalentOperation(s)

BC k       Branch on Carry     BTFSC 3,0
                               GOTO k
BZ k       Branch on Zero      BTFSC 3,2
                               GOTO k


Looks to me like this is an infinite loop when the carry flag is set on
entry to your code snippet ... unless the interrupt handler does not
save/restore the STATUS register and modifies the carry flag!
