Hmm, I had assumed that this was not working because of the file locking
stuff in the report. It works both with and without -threaded with CVS
GHC for me. So, is this a bug in CVS GHC or in 6.4?


Thanks

You need to compile with '-threaded' to avoid this problem.

Unfortunately, this doesn't mean that your program will
actually work. ;-) GHC 6.4 produces a binary that waits
forever. When compiling with the current GHC from CVS,
everything is good:

  $ ghc-6.5 -threaded --make test.hs && ./a.out
  Chasing modules from: test.hs
  [1 of 1] Compiling Main ( test.hs, test.o )
  Linking ...
  ExitSuccess
