ouch, that is a bug in the shell. unfortunately, when you do

	for (i in $var)

$var's value does not get copied into a temporary space if $var is
overwritten in the body of the loop. Nothing gets re-evaluated,
but there are pointers pointing into outer space in a loop like
that.

The fix is not difficult, but spans three source files (I just
fixed the bug).

I don't know how the list feels about this, but there are maybe 2
or 3 bugs in rc-1.2 that I've heard of so far. I don't know how
important it is to release patches, etc. etc., seeing as I've never
done this sort of thing before. I was hoping that rc-1.2 would be
definitive, i.e., any further changes to the shell would be just
bug fixes. How do I go about scheduling fixes like that?
