    Strange problem executing

    Hi everybody,

    What does this execution problem means?

    *** glibc detected *** corrupted double-linked list: 0x083c3538 ***

    thanks a lot,

    Marcelo

      In all likelihood, it is one of the many possible manifestations of
      undefined behavior. If this is the only error message you got, and you
      have no idea where it may originate, you have my sympathies. It would
      be a lot easier to solve if you had a backtrace or core file, or repro
      steps, or a general idea of what the program was doing when the error
      arose.

          I see,

          I was trying to transpose a matrix, is it possible to have this error for an
          out-of-bounds exception?

          thanks,

          Marcelo

              Yes and no:
              No: it is not because an exception is thrown, instead
              Yes: its most likely because you write outside the bounds of your
              matrix thus corrupting the double-linked list: node->next->previous !=
              node.

                  You probably assigned something to an invalid pointer somewhere in your
                  program.
