I wanted to write a function which is supposed to filter RhoCandList objects not by removing items out of a list, but by adding it to a new one. Therefore, I wrote the following function, but it does break when I try to run it and I really don't know why. Below the code is the error message.

int SelectGoodFitStatus(RhoCandList lOld, RhoCandList &lNew) {
	int removed = 0;
	for ( int ii=lOld.GetLength()-1; ii>=0; --ii ) {
		if ( !( lOld[ii]->GetRecoCandidate()->GetFitStatus()>0 ) ) {
			removed++;
		} else {
			lNew.Add( lOld[ii] );
		}
	}
	return removed;
}
