Cbc with GLPK v4.65 incorrect solutions

[joaquinco]

I'm building cbc with glpk integration on branch master, everything runs ok and I'm able to run the solver and seems to run ok, but it doesn't solve the problem correctly (the objective value is not correct and all variables displayed are zero).

I'm calling Cbc like this:

cbc model.mod%data.dat -solve -gsolu solution.sol

Command used to build Cbc:

coinbrew build Cbc --with-glpk

Then, if I changed the Glpk version to 4.48 (for example commit ce1105a of this repo) and I rebuild Cbc, it works fine.

Worth noting that the compiled glpsol works fine on both versions if run on its own.
