Interesting. I was able to reproduce it on debian using x86. I also
noticed that it seemed to be related to the exception handling. If I
catch all exceptions at the highest level (that is add one more level
of exception catching) then the crashing goes away.
Thanks,
Jason

Wolfgang, does it happen for you?

Hello,
I have discovered that when using forkOS and exitWith that I get the
following error:

I'm using OSX 10.4, and ghc 6.4 from darwinports.
Thanks,

I have attached a relatively simple program that demonstrates the
crash, here are steps to reproduce the crash:
$ make
ghc -threaded --make Hud.hs -o hud
Chasing modules from: Hud.hs
Compiling Main ( Hud.hs, Hud.o )
Linking ...
ghc -threaded --make Connector.hs -o connector
Chasing modules from: Connector.hs
