 Hello,

 I use the last version of CBC (2.8.3).
 The problem has been met under windows 32 + 64 and linux 64.

 I added the Dynamic3 heuristic like this:

 CbcHeuristicDynamic3 HeuristicDynamic3;

 HeuristicDynamic3.setModel(pModel_l);
 myCbcModel->addHeuristic(&HeuristicDynamic3);

 Then I started the resolution using the Osi layer of CBC.

 Here is the gdb log:
