[MLton] Overflow Exception

[Raymond Racine]

Hey Steve,

I did try -exn-history true.
Ran in strace as well along with a C compile with cc-opt -g  in gdb to
see what I could see.  But I'm not facile in these areas.

It appears the handler [ ... handle exn => app print (MLton.Exn.history
exn)] around main is not being called. 

In fact it appears to die pretty much on exe "start-up".

Even though the code itself is pretty small I had lots of dependencies
on the smlnj-lib, SMLNJ Regexp stuff.  So I'll need to pack up and send
a chunk of stuff if it comes to that. 

I'll do more due diligence on my end so I'm not wasting your time and
then tar it up and ship it off if I don't see something.  I was sort of
fishing around for some kind of magic debug/compiler setting.

In order then,

#1. Attempt with MLton 200402027 
#2. Double check a few things.
#3  tar up a ready to go test case and mail it off to you.

Regards,

Ray
