    Multidimensional array: read errors?

    Am using Metrowerks CodeWarrior, and I am working with a two-dimensional dynamic array.

    Sometimes the nested loop
    for(i=0;i<r;i++)
    {
    for(j=0;j<s;j++)
    {
    do_something_to(array[i][j]);
    }
    }

    doesn't quite behave as it should. After significant debugging, I have found that it doesn't always retrieve the array value it's supposed to. For example, when i=4, j=0, it retrieves array[0][0] instead of array[4][0].

    Does anyone know how this might be fixed?

    That sounds suspicious...Does it only happen with dynamic arrays? Maybe you could post a short example program that we can compile.

    Post the declaration of do_something_to(...).
