[Coin-discuss] SBB, AllowableGap and Cuts.

[Edwin Straver]

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.
