    Segmentation Fault

    Hi!

    What are the reasons for a segmentation fault?

    My program doesn't always cause a segmentation fault, only sometimes although the program flow is exactly the same. Do you have any ideas?

    I'm using RedHat Linux and KDevelop.


    Thanks and best regards
    Haos

    When you try to access memory that you're not supposed to, you get a segmentation violation. Typically this can happen when you're working with arrays and pointers.

    Some times you get lucky and some times you don't.

    >What are the reasons for a segmentation fault?
    Accessing memory outside of your address space is the #1 reason. Make sure you aren't writing somewhere that you shouldn't be first thing.
    My best code is written with the delete key.
