Question

    unsigned int j   = 0;
    openListIterator = openListVector.begin ();
    while (exitPointDetailsVector[lowestWeightedPointInOpenList.pointId].branchesVector[m].connectedExitPoint >= openListVector[j].pointId)
           && (openListIterator <= openListVector.end()))
    {
        // Move the iterator.
        openListIterator++;
        // Move the index.
        j++;
    }

    // Insert in the vector in the required position.
    listStruct objOpenListStruct;
    objOpenListStruct.pointId       = exitPointDetailsVector[lowestWeightedPointInOpenList.pointId].branchesVector[m].connectedExitPoint;
    objOpenListStruct.weight        = exitPointDetailsVector[lowestWeightedPointInOpenList.pointId].weight + exitPointDetailsVector[lowestWeightedPointInOpenList.pointId].branchesVector[m].distance;
    objOpenListStruct.parentPointId = exitPointDetailsVector[lowestWeightedPointInOpenList.pointId].exitPoint;

    ***********openListVector.insert (openListIterator, objOpenListStruct);

This code is under a for loop.
But I have put the proper the iterator initialization, still I am getting a segmentation fault, on the starred line.

Any hints?

Answer 1

In the statement openListIterator <= openListVector.end(), if you reach openListIterator == openListVector.end(), then you’re going to have a segfault, because when the code reaches openListIterator++, your iterator becomes “out of bound”

Try openListIterator != openListVector.end()
