GNUstep apps segfault on AMD64

[Tim Schmielau]

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 
libffi 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 GNUstep installations based on various libffi versions
(including 3.0.5 and the one from gcc-4.2.4) as well as ffcall, same effect.
I've updated base to 0.16.1, no change.
gcc, libffi/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
