    Problem Summary TSD4U.00170 This test may fail due to memory management logic errors.
    Problem Text
    test purpose 12 of sockets/sendmsg fails (see report output).
    There are two deficiencies:

    o The test case tries to allocate memory of large size
    [f(ssize_t]. This allocation failes because of restricted
    stacksize ("ulimit -s": 16MB). Then the test continues with
    a smaller size and fakes the allocated address by sbrk(0);
    [This is ok because it shouldn't access it anyway!]
    But:
    when succesfully (or errorneous) completing the test,
    then the faked allocated address is being freed by free():
    ==> SIGSEGV and test failure.

    Solution:
    remember whether the memory really was allocated and
    only free it in this case.

    o when initializing "Siovec" the index into the array may
    exceed the valid range:

    #ifdef VSU411_Coding
    Siovec[i+1].iov_base = Siovec[i].iov_base;
    #else
    if(i > 0)
    Siovec[i].iov_base = Siovec[i-1].iov_base;
    #endif
    Test Output
    TEST PURPOSE #12
    If the implementation supports a communications domain
    and a socket type:
    EINVAL in errno and return -1 on a call to ssize_t
    sendmsg(int socket, const struct msghdr *message, int
    flags) when the sum of the iov_len values overflows a
    ssize_t.
