--- Comment #1 from Roderick Colenbrander thunderbird2k@gmx.net 2008-10-18 16:10:37 --- Running out of virtual memory is a known issue. In short Wine reserves huge parts of virtual memory in order to emulate the windows memory layout properly. Unfortunately there is not that much virtual memory left for native libraries (only 200-300MB or something like that). Especially OpenGL is senstive to this. We need to remap linux memory calls to wine, so basically we have to map linux malloc to win32 heapalloc, so that native libraries can use wine memory and not suffer from the VM limitation. You could say that this bug is related to bug 13335 as both are caused by the same VM limitation.
