Err, this is because GCC is extremly stupid. It loads a stack structure 
into ebx, and then the callback code becomes jmp(%ebx).
The problem is that it restores protected registers before doing the 
jmp, so ebx is reset to it's value before the function is called...

I guess this needs to be made __volatile, but I'm afraid that this sort 
of bug might happen in other DLLs. Does anyone know if gcc team is aware 
of this?

Best regards,
