I fixed some things in the program that command calls and now it all
works.
However, I still get the **** string overflowed buffer **** in the debug
output.
So I guess it was a red hering.
Something else I notice below (in case it helps anyone):

That argv[3] was the result of a fancy lookup. If I simply put the
final@??? in the argument list instead of the lookup, the
**** string buffer overflowed **** goes away.
That's not practical, of course, but maybe interesting to someone.
