    stack smashing error

    what the heck does this mean:
    Code:
    *** stack smashing detected ***; ./Prog terminated
    Aborted (core dumped)
    I understand the core dump, but what's with stack-smashing?

    My program worked fine, but it seems when the destructors were called is where the error occurred.

    You've done something terrible wrong to the stack, simply put.
    Overwriting the end of an array, perhaps?

    Very likely, there's too many darned-arrays in this program, I think its time i re-evaluate things and start trimming some fat...

    No time to start tracing things now though, I must go to class...

    If so, then I suggest you use std::vector and the member function at. It will throw if you try to access out-of-bounds.

    Or valgrind. It will give you the exact line number where you go out of bounds.
    All the buzzt!
