I'm unable to reproduce the effect. Glpsol with default options has no problem on solving Mathieu's example. If --norelax option is specified, the primal simplex falls into infinite loop, but this might be expected, because Harris' ratio test (that is, --relax option used by default) decreases the number of degenerate steps and thus prevents cycling in many cases. If the primal simplex fails, I'd recommend using --dual and --flip options.
