Comment:
The user doesn't provide the specific error, but based on the location
(CbcTree::bestNode, call to pop_heap) I'm going to guess that the problem
here is an assert failure (something like `invalid heap') that actually
originates in the MS debug heap implementation. Cause: cbc was altering
the node evaluation method without actually rebuilding the heap. Because
of this, the heap appeared corrupted (nodes in the wrong place). This is
now fixed.
