    Problem Summary PG4U.00160 This request disagrees with the test logic.
    Problem Text
    In the above output, it shows that the tests are failing because lseek is
    failing, returning a errno of 22, which on our implementation is EINVAL.
    The tests are attempting to seek beyond the allowable maximum filesize.
    Page 489 of the XPG5 XSH states the following:

    "ERRORS
    The lseek() function will fail if:
    .
    .
    .
    [EINVAL] The whence argument is not a proper value, or the resulting
    file offset would be invalid.

    PIN5.003 confirms that this is proper behavior for the lseek() function.

    Review Response
    We recommend this request be refused.

    We believe this test is correct as written. Before calling lseek() the
    test sets RLIMIT_FSIZE beyond where it seeks to and hence is not
    seeking beyond the maximum file size.
