Using Clp/stable/1.7 and Osi/stable/0.98, I get an error
when using the following commands on the attached mps file bug3.mps.
OsiClpSolverInterface *master_clp = new OsiClpSolverInterface;
master_clp->readMps("bug3.mps");
master_clp->setupForRepeatedUse(3,0);
int pos[10];
double bnd[10];
OsiSolverInterface *clpB = master_clp->clone();
pos[0] = 12;
bnd[0] = 1.0;
bnd[1] = 1.0;
pos[1] = 13;
bnd[2] = 0.0;
bnd[3] = 0.0;
clpB->setColSetBounds(pos, &(pos[2]), bnd);
clpB->resolve();
I get incorrectly that the optimal value of the LP is -5. When I comment
out
master_clp->setupForRepeatedUse(3,0);
I get the correct result -6. Valgrind sees a single error (in both cases,
so it might be unrelated):
