I didn't try to run Gorm in gdb because sometimes it runs fine !

An other weird behavior : if i uncomment an other NSLog (always
in the same Win32CairoGlitzSurface method) i get a glitz error
'couldn't find ARGB32 surface format' (glitz_find_standard_format)
_before_ the execution of the new NSLog (but at the 2nd invocation
of the method).

I dont understand how a std output can corrupt a program or
change the result of an opengl(glitz) call.

IMHO the reason of all this is either :
 - a gcc 4.1 bug
 - a mingw bug
 - a video driver bug
 - a wrong library configuration
 - a thread conflict
 - another weird thing i cant understand

Here is a try with gdb in a case where Gorm cant start and ends
with 'couldn't find ARGB32 surface format' (exit 1).
See a full backtrace below - i dont understand anything :o\
The call came from ntdll.dll, from atioglxx.dll, from libglitz-1.exe, from
ntdll.dll, from atioglxx.dll, from -[NSTableView highlightSelectionInClipRect:]
But first gdb gives a warning :
  warning: HEAP[Gorm.exe]:
  warning: Invalid Address specified to RtlReAllocateHeap( 003D0000, 014C53A0 )
My gdb seems buggy :-\

I see a call to 'ntdll!RtlFreeThreadActivationContextStack'
Could it be a thread conflict error ?

Gorm GSBackend is default to 'GlitzCairo-012', that's the name
of my backend. But each time i launch Gorm, i get :
'Did not find correct version of backend, falling back to std.'
I dont know what that means. Could it be the reason ?
Same message with Calculator or GFractal examples
(the last is very very sloooooowww)

Any ideas ? Thanks :-)
