Ah yes, you are right! However, in my stupidity, I might have stumbled onto
a clue. The solution that Clp is giving me before solving on the command
line is precisely the one I am seeing from within SYMPHONY. Inside
SYMPHONY, I am definitely making the solve call first. It doesn't seem like
that can be a coincidence. What is this solution it produces before solving?

It's SYMPHONY trunk. I'll check in my code and send you the details of how
to reproduce in a separate e-mail. Thanks!

Cheers,
