CBC crashes on windows machines

Description

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 Build Date: Dec 10 2018

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
