#29: OsiClp crashes on an ILP

     Type:  defect    |      Status:  new   
 Priority:  blocker   |   Milestone:        
Component:  OsiClp    |     Version:  0.95.2
 Keywords:  IP Solve  |  
----------------------+-----------------------------------------------------
 I modified the basic.cpp in Osi examples so that it solves my IP. However,
 it crashes in the call to osi->branchAndBound(). Here is the log.

 To recompile, you need to replace the Osi/examples/basic.cpp with the one
 in the tar ball.

 This is truly a blocker for me. I am developing an application using BCP
 framework and I can not proceed until I can solve the IP similar to this
 example.
