[PPL-devel] Bug in glpk 4.21?

[Roberto Bagnara]

For the attached testcase, we obtain that

$ glpsol p0033.mps --max -o output.gomory --gomory

gives an optimum of 5201, while

$ glpsol p0033.mps --max -o output.intopt --intopt

gives an optimum of 5131.  The optimum 5201 is confirmed
by a completely different MIP solver.
Does this behavior indicate there is a bug somewhere?
All the best,

     Roberto
