Running heuristics on CbcModel outside branchAndBound

[IlyaShaternik]

Hi!
I would like to know if it is possible to run heuristics without calling branchAndBound on CbcModel? I was trying to do it like so:

    CbcHeuristicFPump heuristicFPump(*cbcModel);
    heuristicFPump.setWhen(3);
    heuristicFPump.setNumberNodes(200);
    heuristicFPump.setFeasibilityPumpOptions(40);
    // ... some other settings
    cbcModel->addHeuristic(&heuristicFPump);

    double obj;
    std::vector<double> new_sol(cbcModel->solver()->getNumCols(), 0);
    heuristicFPump.solution(obj, new_sol.data());

but it doesn't work. CbcHeuristicFPump exits before doing any work, but if I run branchAndBound everything runs as expected.
