I think there's a bug in the support for 'foreign export dynamic'. The 
enclosed code crashes intermittently. Sometimes it does this:

$ ./FEDBug
Haskell: making callback
Haskell: calling callback
native: calling callback
Haskell: haskellFunction
native: done calling callback
Haskell: done

And sometimes it does this:

$ ./FEDBug
Haskell: making callback
Haskell: calling callback
native: calling callback
Illegal instruction

It's about 50/50 on my MacOS X machine. The same code never crashes on my 
Linux/i386 box.
