 Hi,

 I have downloaded CBC 2.4 and try to use it on Windows 7.
 My development environment: Microsoft Visual C++ 2008.
 I compiled in Debug mode, and run sample2.cpp on flugpl.mps.
 I did not add any cut generators.
 The crash occurs in CbcModel::branchAndBound line 3910.

 This problem is even more mysterious because whether tree search crashed
 or not depended on the cut generators I added.
 Experiment 1) I added Gomory cuts, and the program terminated properly.
 Experiment 2) I added CglLandP cuts, and CBC crashed, but now at a
 different location: CbcModel::branchAndBound(), line 3681,
 and inside that CbcTree::bestNode(double cutoff=1.0000000000000001e+050)
 Line 273.

 Thank you for providing some feedback.
