Dear GLPK Team,

I have an mip problem (see attachment) that can be solved in under a
second with glpk 4.58 but loops with glpk 4.64. That is, the gap does
not go below 0.3% no matter how much time I keep running the solver.
Gurobi also finds the solution (the same one that glpk 4.58 obtains). I
would be very grateful for any feedback!
