I am trying to compile a linked program for a 12c508 and have noticed that somehow, extra instructions are being included in the program code. These are shown in the map file as .cinit ROMDATA at some location and are always 4 bytes long. If you look in the program memory these extra instructions are shown as RETLW 0x00. I've tried to find it in the program files but their location seems to be after the END instruction of the MAIN program file and before any linked file.
Any help greatly appreciated
