Running a linear programming problem always generate an access violation #371

Hello,

I'm using Windows 10. I've installed hmatrix and hmatrix-glpk today, with the libraries openblas and glpk. Each time I try to run a linear programming problem, such as the small one given in example, I get an access violation error. This occurs with simplex and with exact.

ghci> simplex prob constr []
