See the attached code. Use "make" to compile and you should get an executable file called "Bug.bin", then you can run it by typing the command "./Bug.bin N" where N is the number of concurrent threads.
For N<=32. The program works fine. It will simply loop and you need another terminal to kill it.
For N>32, it always crashes immediately:
$ ./Bug.bin 33 Bug.bin: internal error: too many workers; runaway worker creation? (GHC version 6.5.20060620 for i386_unknown_linux) Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug Aborted
