    Bug summary: If pthread_create fails in aio_write, requests linked list is corrupted
    Bugzilla link: https://bugzilla.redhat.com/show_bug.cgi?id=566712

    Description:

    Description of problem:
    When one calls aio_write, it internally calls __aio_enqueue_request, which will in turn call aio_create_helper_thread.  If thread creation fails, the newly created request (newp in the code) will still be in the requests linked list, but it will be freed later in __aio_enqueue_request.

    A subsequent call to aio_write will cause a segmentation fault.

    Version-Release number of selected component (if applicable):
    glibc-2.5-*.el5

    How reproducible:
    100%

    Steps to Reproduce:
    There's a test case from Neil Vachharajani in upstream bugzilla:

    http://sources.redhat.com/bugzilla/attachment.cgi?id=4198&action=view

      
    Actual results:
    If compiled -DCRASH the program segfaults.

    Expected results:
    If compiled -DCRASH the program does not segfault.
