GHC doesn't work with Data Execution Prevention on Windows
ghci crashes just after startup, usually after displaying:
"Loading package base-1.0 ... linking ... done."
I get this message:
<<< ghc.exe - Application Error
The instruction at "0x1169f890" referenced memory at "0x1169f890". The memory could not be written
I've got a debugger that shows a dissassmbly. This is an extract (I can show send more if you want, I'm guessing it's not very useful).

My computer is an AMD Athlon 64 X2 Dual, Core Processor 4400+, 2.22 GHz, 2.00 Gb RAM. If I turn off Data Execution Prevention for the ghci process (under System Properties -> Advanced -> Performance -> Settings -> Data Execution Prevention) , ghci continues as normal and works.
I have noticed sometimes that even with the Data Execution Prevention enabled, it doesn't crash. It seems to go in phases. I think I've seen the same thing with ghc, as well as ghci, I can test more if required.
My version of ghc is 6.4.2, from the Windows .msi installer, http://haskell.org/ghc/download_ghc_642.html#windows
