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

[Ted Ralphs]

As an alternative, I'm in the process of rolling out automated deployment
of binaries and this is a good chance for testing that. I'd appreciate if
you could check out the binaries here:

https://bintray.com/coin-or/download/Cbc/2.9#files/

and let me know if they work for you. These are built against the latest
commit in the stable 2.9 branch. Trunk (development version) builds are
also available. These binaries are built, tested, and deployed
automatically from either Travis (Linux and OSX) or Appveyor (Windows)
after each commit. Starting with the next release, binaries will also be
deployed automatically immediately following each release. Let me know how
it goes.

Cheers,

Ted
