I don't have a solution but some ideas:
- If you're using the Plus/4 target, the program uses banking. You you
  sure anything is ok with the ROM being correctly banked in and so on?
- Can this be because the routine leaves interrupts disabled?
- The generated C code isn't reentrant. I usually recommend against 
  writing interrupt handlers in C. Are you sure you don't have a
  reentrancy problem?
