Do you have a reproducer script I could try?  I think your
reading of the code is correct.  It's trying to take the
something like:

	x = frob(a, b, c, d);

and create a fake assignment:

	x = d;

And, I guess, it can't find 'd'.  But my line numbers in mdb_nv.c are
different from yours.

There seems to be an obvious fix which I have done and pushed
but I can't test it.  Could you give it a shot?
