I don't know what revision of the compiler you are using, but some older
revisions had some trouble with indirect addressing registers. If you
are using an older version, please upgrade to latest or at least use
large memory model & 16-bit stack.

IMHO better is to use:
#pragma interrupt high_isr
save=PRODL,PRODH,section(.tmpdata),section("MATH_DATA")

- .tmpdata has to be saved if you call a C-function from the interrupt
function.
- MATH_DATA has to be saved if you use floating point variables in any
way during interrupts

New manual has quite good instructions how to make interrupts, download
it from the website.
