#102: cbc stand-alone solver aborts unexpectedly

---------------------+------------------------------------------------------
 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.
