weird activation record found on stack
Hello. I got this one off.

internal error: scavenge_stack: weird activation record found on stack: 0
Hello,
I have discovered that when using forkOS and exitWith that I get the
following error:
hud: internal error: scavenge_stack: weird activation record found on
stack: 0
Please report this as a bug to glasgow-haskell-bugs@haskell.org,
or http://www.sourceforge.net/projects/ghc/
I'm using OSX 10.4, and ghc 6.4 from darwinports.
Thanks,
Jason
I have attached a relatively simple program that demonstrates the
crash, here are steps to reproduce the crash:
