getMBlocks: VirtualAlloc MEM_RESERVE 1 blocks failed

Garrett Morris writes: I've been running into the following error:

Reproduction.exe: getMBlocks: VirtualAlloc MEM_RESERVE 1 blocks
failed: Not enough storage is available to process this command.

The confusing part to me is that when the error occurs, Task Manager reports that the process is using around 100K of memory, while I know that the machine has at least 2GB available.

Reproduction case is attached. This runs against the Netflix prize training set, which is large enough that I haven't attached it. At the time that the error occurs, it's processed on the order of 15,500 files. Is it possible there's some other resource that I'm exhausting without realizing it?

The compiler command line is:

ghc --make -O2 -threaded -hidir obj -odir obj -o Reproduction Reproduction.hs
