    14 The fact that Sage crashes hard is handled at #19525.
     13With #19525, this improves to not crashing Sage:
     14{{{
     15sage: sage: p = MixedIntegerLinearProgram(solver="glpk")
     16sage: sage: q = MixedIntegerLinearProgram(solver="glpk")
     17sage: sage: q.add_constraint(p[0] <= 1)
