<br><font size=2 face="Arial">Hi All,</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">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.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">This is the line:</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">if (!nodeOnTree)<br>
delete node;</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">I think when SBB stops when an allowable
gap has been reached, and cuts have been generated, this can cause a problem.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">When I change the code to:</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">if (!nodeOnTree && !stoppedOnGap)<br>
delete node;</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">everything runs fine for me, and I do not
see a memory leak.</font>
