 The test around line 101 ({{{srRowCut2 == solRowCut}}}) fails because it
 assumes an ordering for indices in the packed vector returned from the
 cut. Different underlying solvers will produce different orders.

 This will test for mathematical equality, not structural equality;
 critical change is isEquivalent:
 {{{
 assert(srRowCut2.OsiCut::operator==(solRowCut)) ;
 assert(srRowCut2.row().isEquivalent(solRowCut.row())) ;
 assert(srRowCut2.lb() == solRowCut.lb()) ;
 assert(srRowCut2.ub() == solRowCut.ub()) ;
 }}}
