    Problem Summary TSD4U.00033 tests may fail on implementations where PATH_MAX > _POSIX_PATH_MAX
    Problem Text
    The tests listed above may fail on systems where _POSIX_PATH_MAX
    is less than PATH_MAX.

    The tests use _POSIX_PATH_MAX as the size of the char array
    that the pathname will be returned in. The getwd XPG spec
    states this array size should be PATH_MAX bytes to store the
    longest possible pathname.

    On our system PATH_MAX is 1023 and _POSIX_PATH_MAX is 255.

    The array is to short and the tests write past the end of it.
    This corrupts the stack and causes SIGILL failures similar to the
    example output above for the listed tests.
