I was getting out of memory errors using Hi-Tech PICC-18 with an 18F452 
at around 50% ROM usage.

Hi-Tech support told me it was due to a bug in the silicon and the fix 
was to split my program into multiple files which could be linked 
separately.

No further problems since doing this.

Regards,

Nigel
