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
