    Please report this as a GHC bug:  http://www.haskell.org/ghc/reportabug

Please contact the application's support team for more information.

I don't know if it is of any use to you but here is windows' problem signature:

I had following ghc extensions enabled: ExistentialQuantification?, ScopedTypeVariables?, NamedFieldPuns?, DeriveDataTypeable?, ParallelListComp?. Re-runing the same expression didn't cause repetition of error. Program was supposed to be browsing over directories of local disk.

My OS is Windows 7 x64 SP1.

If you need other information I will try to help.

Can you reproduce the problem?

Replying to simonmar:

Can you reproduce the problem?

Unfortunately I was unable to reproduce the problem. I tried repeating same steps as in crash case but it runs OK now.

Probably a transient hardware problem then.
