Description

I try to solve a MIP with the cbc stand-alone solver (2.5.0, build Sep 7 2010), but it aborts unexpectedly with the following line:

cbc: CbcBranchDynamic?.cpp:549: virtual int CbcBranchDynamicDecision::betterBranch(CbcBranchingObject?*, CbcBranchingObject?*, double, int, double, int): Assertion `distance >= 0.0' failed.

I'll attach the log and the mps input, hth.
