[Haskell-cafe] FFI in threaded mode (was Re: New runtime crash, not sure what to make of it)

[Joel Reymont]

The program runs fine in non-threaded mode, including from within  
ghci. The crash below hapens when using -threaded.

I tried to come up with a repro case but could not reproduce the crash.

	Thanks, Joel
