There is a comment that this is a Windows limit, but AFAIK it is not present on x64 Windows, so probably it can be changed for LARGE_ADDRESS_AWARE programs, to allow them to use all the address space.

I change in dlls/ntdll/virtual.c two lines: # define ADDRESS_SPACE_LIMIT ((void *)0xc0000000) /* top of the total available address space */ # define USER_SPACE_LIMIT ((void *)0x7fff0000) /* top of the user address space */ to # define ADDRESS_SPACE_LIMIT 0 /* no limit needed on other platforms */ # define USER_SPACE_LIMIT 0 /* no limit needed on other platforms */ and compile Wine. As a result it possible to allocate about 3600 GB for windows application (openSUSE x64 +Wine 1.0)
