Bug 690882 - (cov#10572,10710) Incorrect sizeof use in uuid code
    
    When sizeof() is called at line 943, it is calculating the size of
    a pointer, not the array. This happens since the array was passed
    to get_random_info(), which considers it to just be a pointer. The
    result is that we do not fill in the full array with random data.
    We should pass the array length to this function instead of using
    sizeof().
