Yeah, actually matt's suggestion worked.  I used:

   double *d = new double[N];

to allocate my arrays and it worked fine.  I never bumped against a stack
size limit before.  the stack size limit as reported by ulimit is 2MB.  That
seems pretty restrictive.

No problemo.  My only concern is to learn and become better.  Everything is
appreciated graciously.

Yeah, that's me.  Working on Wall street is a gas.  Last night I got drop
dead drunk doing shots at Fraunce's Tavern (where George Washington said
farewell to his officers) with a friend and a CTO of a major financial
software firm.  Turns out the guy is a Davis native (!) and a fellow
physicist.  He went the equities route, and as for right now, I seem to be
headed for fixed income.

I have to say, I always felt for the talented people on this list who were
out of work, but in retrospect, I never really understood just how
demoralizing it really is until it happened to me.
