The files that I've seen it occur on were:
and a self-compile.
The only other thing I can possibly think of might be that I was
(SML/NJ) recompiling MLton while the regressions were going. I don't know
what NJ does if it's image file is rewritten while it's running -- I would
have assumed it loads it all in at invocation. But I wouldn't have done
that on the self-compile, since I set that going before I left last night.
