Crashing Hugs for fun and profit

By tweaking the code a bit I was able to get GC messages, but the
examples above crash. I suspect the crash is rather fragile - minor
alternations like removing expressions that seemingly have no
interaction fix this crash. I suspect it will be hard to replicate
unless you use the actual binary from WinHugs.

I have replicated this on my other Windows machine, with the same
binaries, and the same result. Perhaps running this example under
Valgrind will show up something?

Thanks
