I'm on a 64bit version of windows here with more than 4GB of memory to spare
for the GHC process. Unfortunately, allocaBytes takes an Int so I can't test it with a request larger than the amount of physical ram I have.
It would seem that the Haskell Platform for windows only ships a 32 bit binary. That is rather unfortunate: $ ghci +RTS --info WARNING: GHCi invoked via 'ghci.exe' in *nix-like shells (cygwin-bash, in partic ular) doesn't handle Ctrl-C well; use the 'ghcii.sh' shell wrapper instead [("GHC RTS", "YES") ,("GHC version", "7.0.2") ,("RTS way", "rts_thr") ,("Build platform", "i386-unknown-mingw32") ,("Build architecture", "i386") ,("Build OS", "mingw32") ,("Build vendor", "unknown") ,("Host platform", "i386-unknown-mingw32") ,("Host architecture", "i386") ,("Host OS", "mingw32") ,("Host vendor", "unknown") ,("Target platform", "i386-unknown-mingw32") ,("Target architecture", "i386") ,("Target OS", "mingw32") ,("Target vendor", "unknown") ,("Word size", "32") ,("Compiler unregisterised", "NO") ,("Tables next to code", "YES") ] With a 64bit build, perhaps I could experiment more. I looked at the Haskell Platform page and I don't see a 64bit version. It would seem the binary from GHC HQ has the same limitation since there is only one installer and it claims to work on windows 2000: http://www.haskell.org/ghc/download_ghc_7_0_3#windows Jason
