#144: Crash of 2.8.8
-------------------+-----------------

-------------------+-----------------
Hi
I updated from 2.8.3 to 2.8.8.
After that cbc crash after 16'000 seconds without error message, with
version 2.8.3 the same mps file works.
I'm not a mathematician, but the developer, so I have no clue about the
content of the attached mps file which cause the crash.
This is the log content:
