Description
Instead of the standard 2 GB of user address space given to 32-bit processes on Windows, programs built with the /LARGEADDRESSAWARE linker switch are given a 4 GB user address space when running under a 64-bit OS. Comparing builds without and with /LARGEADDRESSAWARE, VMMap shows that we go from a total of 1950 MB of free address space to 3978 MB free. The addition is a block of just under 2 GB starting at address 0x7FFF0000.
