when attempting to symify an EXE I compiled with GCC 2.952, it crashed down
to this:

Exiting due to signal SIGSEGV

I was using the SYMIFY from the binary distribution of djdev203.zip.

The command line I used was:

symify edge.exe

and it crashed both if there was and if there wasn't traceback info on the
screen.

The EXE was rather big (3.2 megs), and if I stripped the debug info, I got
this crash:

Exiting due to signal SIGSEGV

(c:\windows contains an exact copy of 2.03's symify.exe)

My EXE was created from the following stuff:
- Our own C files, compiled with GCC 2.952
- Our own ASM files, compiled with NASM 0.98
- libc
- Newly compiled Allegro version

I haven't posted any of the exes (since they are quite big), do you need a
bz2:ed copy of any of them?
