possible bug

[Suresh Jagannathan]

In running count-graphs, I came across the following
error.  At size threshold 50, the compile runs
smoothly.  Run immediately again (with no intervening
computation), an error is raised in the contifier
claiming a duplicate function label.  Type checking
the inlined output succeeds.  

The reason why I believe this is a MLton bug (as opposed 
to an inliner problem) is the error manifests only 
after the first compile leading me to suspect some 
global property not being cleared.
