We are seeing a segfault from Cbc when
both multi-threading and equal-cost variable aggregation are
enabled. The
segfault occurs right after Cbc works through its root cuts. The
Cbc version is the trunk build of March 20; it's not stable
because Dr.
Forrest had just added equal-cost variable aggregation.

Here is a log of Cbc output. I
can supply an MPS model, but it's the same one I sent to Dr.
Forrest in
March.

I have a faint recollection of getting something similar after March
20 when I was doing more testing - so I think I may have fixed it
since then. It is fine when I try it with the latest trunk.<br>
<br>
So try latest trunk and tell me if you have problems.<br>
