Comment:
The source code (`Cbc/src/OsiCbc/OsiCbcSolverInterface.cpp`) suggests
we're doing the right thing: when supplied a solver, the constructor tries
to clone it. I can see that they carry out several further steps, cloning
the solver again, but that's for a different class member
(`referenceSolver_`). Nothing strikes me as obviously wrong.
I will report it upstream and try to find out what's going on.
