#187: CBC crashes on windows machines

--------------------+-----------------
Dear all,
I am trying to solve the attached lp model with CBC on a 64 bit windows
machine with Visual Studio 2013.
The problem is that CBC crashes before finishing Branch&Cut. I tried with
different CBC versions: CBC 2.7 (stable), CBC 2.9 (stable), trunk, and CBC
2.9.8. The same error occurs in the same place. I converted the lp file to
an mps file and it crashed again.
Attached are the .lp (compressed) and the .cpp files.
Note that on Ubuntu it works fine.
Following is an instance of the log output:
Welcome to the CBC MILP Solver
Version: 2.7

command line - Test -solve -quit (default strategy 1)
Continuous objective value is 80.7531 - 241.00 seconds
Cgl0004I processed model has 306368 rows, 306789 columns (306789 integer)
and 847187 elements
Objective coefficients multiple of 1
Cutoff increment increased from 1e-005 to 0.999
Thank you for your support!
kind regards,
Djamel
