crash when using local display but not remote

[Riccardo Mottola]

Hi!

to test the latest "libart" stuff I upgraded all GNUStep on the old and 
venerable MIPS Book Letux400

I got everything to build! yeah!

If I export the display through ssh, everything works and (albeit 
slow... the Letux had the LAN connected through USB on the board) I get 
a fine looking GNUstep!

If I use it locally, however, I get an immediate crash:

(gdb) r

Previous frame identical to this frame (corrupt stack?)

this does not look very useful and looks like very early memory corruption?

I recompiled all back with debug=yes, I hope that still disables 
optimizations correctl. I do not get a better stack. and not a better 
outcome either!

Could someone using art on x86 or amd64 try valgrind?
