I *think* this should use 3GB on Linux. After all RtlAllocateHeap calls VirtualAlloc which uses raw memory allocation without any 2GB restrictions to be seen anywhere. ICBVW, though.
I think that if Windows allocates 2GB only to user space, then that's it. If Linux allocs 3GB for that, then that's it, too. Wine only plays a minor role in that, AFAICS. -- Andreas Mohr Stauferstr. 6, D-71272 Renningen, Germany Tel. +49 7159 800604 http://home.nexgo.de/andi.mohr/
