This is the glop output:
Solver : GLOP_LINEAR_PROGRAMMING
Dimension : 19 x 10
Initial problem: 19 rows, 10 columns, 28 entries with magnitude in [5.000000e-01, 1.000000e+00]
Objective stats: 10 non-zeros, range [1.800000e+01, 1.000000e+16]
Bounds stats: 21 non-zeros, range [8.000000e+00, 2.703000e+03]
Starting presolve...

FreeConstraintPreprocessor : 0(-19) rows, 9(-1) columns, 0(-28) entries. (0.000002s)
UnconstrainedVariablePreprocessor : 0(-19) rows, 0(-10) columns, 0(-28) entries. (0.000010s)
Reached fixed point after presolve pass #1
Presolved problem: 0 rows, 0 columns, 0 entries with magnitude in [0.000000e+00, 0.000000e+00]
Objective stats: No objective term. This is a pure feasibility problem.
Bounds stats: All variables/constraints bounds are zero or +/- infinity.
Final unscaled solution:
Primal objective (before moving primal/dual values) = 2.559000000000000E+19
Dual objective (before moving primal/dual values) = 2.559000000000000E+19
Max. primal values move = 0
Max. dual values move = 0
Primal objective (after moving primal/dual values) = 2.559000000000000E+19
Max. rhs perturbation = 0
Max. cost perturbation = 1
Max. primal infeasibility = 0
Max. dual infeasibility = 0
Objective error <= 2.559e+13
The needed cost perturbation is too large !!
