32-bit Windows limits processes to 2GB of virtual memory. There is boot switch to increase this to 3GB but I don't know if it is supported. If you really need multi-GB heaps then maybe it is time to switch operating systems.

agreed, or run in parallel but that's no fun

with 32-bit Windows limits processes to 4GB of virtual memory. not 2 GB ...because with process model of OS , 2 ^ 32 = 4 GB

4GB of virtual address space, which is then split 2GB available to the program, and 2GB for the OS, memory mapped devices, etc.So the limit, as stated, is 2GB.
