I meet some problems when I used the funtionObjects about cuttingPlane in OpenFOAM-7. When I try to get more planes, it seems to be a memory leak (Or probably I did something wrong). And I found someone also asked the same questions on "OpenFOAM Issue Tracking" (https://bugs.openfoam.org/view.php?id=1777). I see you modified some codes about cuttingPlane in commit number 5fa3218 and 723f522. So I want to know did those codes fixed it, or my cases mistaked.
