$ defaults write NSGlobalDomain GSBackend cairo
2010-03-16 22:41:33.625 defaults[3576] Defaults path 'C:/GNUstep/Defaults'
did not exist - created it
2010-03-16 22:41:33.625 defaults[3576] Creating empty user defaults
database

Problem is on my harddrive I have 1 GNUstep install in C:/GNUstep
but this is not my current sandbox C:/Developer/Mingw-NG.
So I suppose you are using some kind of registry key with this defaults
stuff...

Finally I have recompiled with default name and I am progressing but
unfortunately
it crashs :

Program received signal SIGTRAP, Trace/breakpoint trap.

(gdb) continue
Continuing.

-------------------

When I let Visual debug it I get :

So problem seems to be inside objc_msg_lookup.


No idea how to fix it.
