In my case I was a solving a small (but very hard) multiple DNA sequence alignment problem:
... Cbc0010I After 132000 nodes, 14298 on tree, -69 best solution, best possible -72.052083 (13292.25 seconds) cbc: CbcTree.cpp:457: virtual CbcNode* CbcTree::bestNode(double): Assertion `best->nodeInfo()->numberBranchesLeft()' failed.
It's probably related to problems informed in tickets #109 and #110
After running CBC in parallel for some time there is this assertion failure:
cbc: CbcTree.cpp:457: virtual CbcNode* CbcTree::bestNode(double): Assertion `best->nodeInfo()->numberBranchesLeft()' failed.
