I got that error "unhandled exception" message first -
then the seg-fault. But I only saw it once when I had
the debug messages in the io-code - so I can't reproduce it.

Well, right now I have the GC-problem under Windows again -
and not under Linux.

I'm sending you (Stephen) an exe-file and a Lightwave object
file which gives the problem. The program is actually going
to be commercial - but since it does not work I don't mind
sending you the .exe :)

Execute it like this:

CeX3DConverter @MLton gc-messages gc-summary -- Triceratops.lwo

I've added a message at every VirtualAlloc and VirtualFree.
It seems to fail after the messages:
Shrinking stack to size 262144
unable to VirtualFree memory at 5ef0000

And by the way - the "unable to VirtualFree" address is hex,
the other virtual alloc/free are decimal.

Do you have any ideas about what this is?
