[Coin-discuss] CLP dual ray broken

[magh at lehigh.edu]

Last time I used OsiClp::getDualRays( ), it was fine. This was about 2 months
ago. Something seems wrong with a recent update. Here is a small test using
itest6.mps from COIN/Mps/Infeas - it retuns NULL for the ray.

#include "OsiClpSolverInterface.hpp"
#include <assert.h>
#include <vector>

int main(int argc, char ** argv){
  OsiClpSolverInterface si;
  si.readMps("itest6.mps");
  si.initialSolve();

  printf("\nSTAT: %d, 2nd STAT: %d",
         si.getModelPtr()->problemStatus(),
         si.getModelPtr()->secondaryStatus());
  
  std::vector<double*> dual_rays = si.getDualRays(1);
  assert(dual_rays[0]);
  
}

Thanks,
Matt
