[Cbc] CBC 2.9.7 crashes after cuts generation at root node

[Anton Kargapolov]

Hi,
My CBC solver consistently crusher when it finds optimal solution at root
node after doing cuts generation.
I attach model, log and screenshot.
Model has ~20000 variables, most of them are "fixed" to specific value by
constraints, and only a fraction of ~20% is to be solved.
I haven't tried 2.9.8 since i can't find the binary for that version. I use
2.9.7 downloaded from AMPL web-page
http://ampl.com/products/solvers/open-source/#cbc

With regards,
Anton
