[Coin-discuss] Bug in OsiXprSolverInterface::getRowActivity()

[Jesper Hansen]

There doesn't seem to be a rowact_ initialized when doing the
CoinFillN(rowact_, nrows, 0.0) below:

const double * OsiXprSolverInterface::getRowActivity() const
{
  if( rowact_ == NULL ) {
    activateMe();

    if ( isDataLoaded() ) {
      int nrows = getNumRows();
      const double *rhs = getRightHandSide();
      if( nrows > 0 ) {
	int status;

	getipv(N_PSTAT, &status);

	if ( status == 7 ) {
	  int i;

	  rowact_ = new double[nrows];
	  solution(NULL, rowact_, NULL, NULL);

	  for ( i = 0;  i < nrows;  i++ )
	    rowact_[i] = rhs[i] - rowact_[i];
	} else {
	  CoinFillN(rowact_, nrows, 0.0);
	}
      }
    }
  }
  return rowact_;
}
