Probably true, but ICD2 breakpoints don't work immediately after some
instructions, particularly ones that modify the program counter.  At least
that is true with the 30F family.  I've never used the ICD2 on a 16 or 18
family PIC.

To be really sure, put two NOPs in a row and set a break point on the second
one.
