I assume that the above is a simplication of a problem you uncovered
when executing "nf_test -c".  Where in the nf_test code is this problem?

A problem in nc_test is more important than one in nf_test (at least for
the purpose of uncovering problems).  Would you please give more detail
on this.

I looked at the problem again (more closely) and decided that I didn't
understand it as well as I should.  It does have the smell of memory
tromping.

First things first, though.  Give me what you've got on the nc_test
problem.
