We run cbc 2.2.2 on linux. CBC is configured with --enable-debug, compiled with gcc 4.1.2. Starting cbc on miplib2003::arkin001.mps with "-rins on -import ~/arki001.mps -branchandC" we receive an assertion:
cbcd: ClpSimplexDual.cpp:1957: int ClpSimplexDual::updateDualsInDual(CoinIndexedVector, CoinIndexedVector, CoinIndexedVector*, double, double&, bool): Assertion `fabs(movement)<1.0e30' failed.
This occurs after about 112000 nodes.
I've attached a file containing screenoutput, call-stack and info about gcc and cbc
Let me know if you need more information
=====
from forrest:
Can get a different error with 2.3. I think it is fixed in trunk but will check
