I can't reproduce problem but as Edwin says changing the code did not seem
to give a memory leak so I have changed the code.

[Coin-discuss] SBB, AllowableGap and Cuts.
Hi All,
When I run the current version of SBB on a model, using CLP with all
available cut generators turned on, and set an allowable "gap" of 5%, I
get crash on line 1023 of SBBModel.cpp.
This is the line:
if (!nodeOnTree)
delete node;
I think when SBB stops when an allowable gap has been reached, and cuts
have been generated, this can cause a problem.
When I change the code to:
if (!nodeOnTree && !stoppedOnGap)
delete node;
everything runs fine for me, and I do not see a memory leak.
