    Default hydra crashes on form based auth

    Hey guys,

    the used hydra release looks buggy, if you are trying to use hydra for hacking into a website with form-based authentication then hydra completely crashes with the following errors:

    Code:
    *** glibc detected *** hydra: free(): invalid pointer: 0x0806ba00 ***

    Hydra (http://www.thc.org) finished at 2009-07-01 11:36:52
    looks like the following problem: http://bugs.gentoo.org/209116

    Edited:
    The patch works! Can someone fix hydra for the final?

    Confirmed. I got the same result before finding this thread. At least it's not user error...this time. :P
