Well, I have been able to build and run egcs-1.1.2 without gpc
with no problems, so if it were a backend problem it should have
to do with gpc at least partly (or the way gpc uses the backend).

I just tried that and got this: 

(gdb) run

I also tried loading xgpc int gdb (which is the executable called
in the Makefile -and I guess it calls gpc1?):


Starting program: /ece2/eeof/gcc/gcc/xgpc -fautomake files.pas
[New process 13613]

        (reg:SI 242)) -1 (nil)
    (nil))
../../../egcs-1.1.2/gcc/p/../toplev.c:1385: Internal compiler error in function

Is there something I should have setup before I do the 'info stack'?
I am not familiar with debugging.

Thanks again,

Dimitrios.

PS. Should I stop cc-ing to the list?
