GNUstep apps segfault on AMD64

[Schmielau, Tim]

I have two quad core 64 bit Xeon machines with SLES 10 sharing the same home 
directory where a fresh GNUstep installation (startup 0.20.0), gcc-4.2.4 and 
ffcall libraries reside. On one of the machines, GNUstep runs fine, on the 
other one every GNUstep application I've tried so far segfaults. For example, 
Gorm gives

I've also tried a GNUstep installation based on libffi, same effect.
gcc, ffcall and Gorm were actually compiled on the segfaulting machine, just to 
make sure (checked a second installation compiled on the other machine, didn't 
make a difference).

Any suggestions?

Thanks,
Tim
