Back when I was doing one of the last GNU ports to the tektronix merlin
(a 32016 machine running utek - a bsd4.2ish system), I ran into this problem
using gas. Basically, the stage 2 binary was mis-assembled by gas so that
one of the common addressing modes (I forget which one, but it involved sb)
was assembled as a reference through the module link table. I happened in
such a way to make cpp exit silently. After about a week of trying to track
it and fix it, I gave up and went back to using the utek assembler (which has
its own problems).

I was using gcc 1.37, and whatever the latest version of gas was at the time (the
32000 port was *very* buggy at the time).

I'm not sure how much this helps, unless someone wants to try tracking it down.

BTW: actually, mine never read the input either, the bug occured in the
code that was processing the -I switches, but I can't quite remember which
function.
