Here is the backtrace from gdb:

when I -fdump-rtl-all-details, I get:
function8.c.104r.expand function8.c.108r.initvals function8.c.111r.jump
function8.c.106r.locators function8.c.105r.sibling
function8.c.109r.unshare function8.c.110r.vregs
I attached them as a TGZ.
Sorry, but i really have no idea where to look anymore. Is there an easier way
to get word-addressing for a 16 bit machine?
