Andrew,
glpk is saying that cont1 found in
http://plato.asu.edu/ftp/lptestset/misc/ has no primal feasible
solution, while other solvers can solve it. I managed to trace it to
an error in the handling of the RANGES statement in mps files, fixed
by the attached patch.
After this fix the solver starts but fails due to singular basis
matrix, but this is another issue.
Best Regards,
Chris Matrakidis
