>From your description it seems the code is the same except fro the
absolute vs. relocatable differences. Look at the .map file the linker
produces to see if the code is in locations where you expect it. In
MPLAB-X there's a bothersome MAIN.O object file that allocated to a
..cinit section. If you're using plain assembly you don't need this and
the linker dumbly puts this code between the reset and interrupt
vectors (or elsewhere).

I'll add a section like this to the linker script:

// http://www.microchip.com/forums/m825351.aspx#825477
CODEPAGE   NAME=3D.cinit   START=3D0xFB0   END=3D0xFFF    PROTECTED    //
Unimplemented memory
SECTION    NAME=3D.cinit   ROM=3D.cinit     // Useless initialization stuff

so the .cinit section is located in a bogus memory area.

I've found no way to prevent that MAIN.O object file from being linked in.
