I'll assume you've got the interrupt vector addresses right...

If there is code there that is more than 28 words long
you'll emit code for address 0x20 and perhaps higher
addresses.

Then you come back and try to set those addresses to
something else, and you get error message(s), starting at
address 0x20. If this is the problem, just put the code
somewhere else and jump to it like you did with the reset
vector.
