No change. Here's the backtrace:

-------------------------------------------------------------
Some additional notes that I should have added in my original post:
- This is gpsim 0.20.12. I got the same errors with 0.20.9 which I had beed
working with.
- The above trace is for Slackware 8.0, gcc 2.95.3, libc-2.2.3.
- I can no longer get my original development machine: Slackware 7.1,
gcc 2.91.66, libc-2.1.2 to crash again. Totally weird and inconsistent.
- Both of these occured after adding my 16 bit integer code to the interpreter.
This significantly changed the code size and list file size.
- The gpsim page needs to be update to indicate that gtk+extra requires the
0.99.16 version. There's a header file missing in 99.9 that is required for
gpsim 0.20.12.
- On both systems everything is fine with just the --cli option. The core
never crashed.
-----------------------------------------------------------------
In truly typical fashion just talking about it make it start working again.
If I get another crash with my normal development box, I'll post it.
