When compiled with SAFEMALLOC or with Windows Debug CRT, it allocates and initializes 5GB of memory. The effect is 20 minutes of paging and swapping on a 4GB VM. Still allow the test to run with optimized binaries. Memory is not initialized in this case, malloc() of 5GB size will not bring the whole buffer into physical memory.
