bug in the Linux student version

[Ali Baharev]

I have obtained the following weird output below. The true number of
constraints after presolve is 280. The benchmark giving this result is
here:

http://reliablecomputing.eu/homoazeo40.mod

Output:

AMPL Student Version 20090926 (Linux 2.6.25.20-0.5-pae)

Presolve eliminates 120 constraints and 120 variables.
Substitution eliminates 760 variables.
Adjusted problem:
280 variables, all nonlinear
280 constraints; 1194 nonzeros
240 nonlinear constraints
40 linear constraints
0 objectives.


Sorry, the student edition of AMPL is limited to 300 variables
and 300 constraints and objectives (after presolve) for nonlinear
problems. You have 280 variables, 1040 constraints, and 0 objectives.
