    Problem Text

    This test is testing for non-required XPG5 behavior:

    The XPG5 XSH states on page 694 states that this is a may fail. Page 138,
    closedir(), states the following:

    "Upon return, the value of dirp may no longer point to an accessible object of
    type DIR."




    This means that the application needs to check the the dirp is valid before
    calling readdir/readdir_r. It is not the responsibility of these system
    calls to determine if dirp is valid. There needs to be a config variable
    like for readdir in VSX4, actually you probably can use VSX_READDIR_EBADF
    since it already in the tetexec.cfg file.

    ----TESE CODE with problem----
    dirp = opendir( "." );
    if ( dirp != NULL )
    {
    rval = closedir( dirp ); ===> dirp will be freed after
    the call to closedir.
    ... ...
    }
    ....

    rval = readdir_r( dirp, pentry, &result );
    ^^^^^
    A freed pointer cause readdir_r to core dump.

    Test Description:
    If the feature test macro _POSIX_THREAD_SAFE_FUNCTIONS is defined:
    when the implementation detects that the directory stream referenced by
    dirp does not refer to an open directory stream,
    then a call to readdir_r(dirp, entry, result) shall fail and return
    EBADF.
