John,

Thanks, the changes seem to have done the trick. My diagnostic for this is pretty crude (Windows task manager), but now peak memory usage does not increase between loops and VM climbs up but does fall back down again.

Have the changes affected CBC brancing behaviour? branchAndBound() now takes longer on my problem and the first solution found is less good than previously,

James


James,

Could not find a memory leak in preprocessing but did find a major one in
CbcModel so try again.

Dual solution after branch and bound not very useful anyway.  Preferred
method for primal solution is CbcModel::bestSolution()
