A segfault in deserializeFromInfo().

[Jefferson Harlough]

Hello. I'm fairly new to GNUstep, and I've run into a slight problem while 
trying to get it working on my system.

I'm using GNUstep Base 1.4.0, GNUstep GUI 0.7.9, GNUstep Make 1.4.0 and 
GNUstep Back 0.7.9. This is on a Pentium4 system running Mandrake 8.2 (Linux 
linux 2.4.18 #13 Mon Jul 15 23:22:24 EDT 2002 i686 unknown). I'm using GCC 
3.1.1 as the compiler, with "-O3 -march=pentium4 -mcpu=pentium4 -mmmx 
-m3dnow -msse -msse2" added by me via $CFLAGS.

I followed some instructions I found on the site as to how to compile and 
configure GNUstep. GNUstep ./configured'ed and compiled fine. The several 
gnustep-base-1.4.0/Testing programs that I tried seemed to run without 
problems (or at least not segfaults).

I proceeded to compile (without problem) the examples in the GNUstep 
Examples 0.9.7 package. However, when I went to run them, I was getting 
segfaults.

Here is the backtrace from GDB when the NSPanelTest is run:

(gdb) run

I could recompile with the "-g3" option if that'll help improve the 
backtrace information.

In any case, the backtraces from the Calculator program were also pretty 
much the same. The segfaults seemed to be in deserializeFromInfo().

Are there any known problems, perhaps when using GCC 3.1.1 with the options 
I mentioned above, that would result in such a problem? Could I have 
forgotten to or perhaps misconfigured something while building and 
installing GNUstep that could lead to this error? Any known workarounds?

 Thanks,
   J. Harlough
