Description

sage: p = MixedIntegerLinearProgram()
sage: q = MixedIntegerLinearProgram() 
sage: q.add_constraint(p[0] <= 1)
------------------------------------------------------------------------
Unhandled SIGABRT: An abort() occurred in Sage.
This probably occurred because a *compiled* component of Sage has a bug
in it and is not properly wrapped with sig_on(), sig_off().
Sage will now terminate.
