The attached file glpk_bug.m runs glpk on data loaded from the attached file
glpk_bug.dat. It should minimise the function c*x subject to constraints of
the form A*x=b or A*x<=b, as specified by ctype. The function runs without
errors (status=0) but finds a minimiser xmin that does not satisfy the
constraints, since (A*xmin)(24)>b(24).
