    Test Suite VSW version 5.0.1
    Test Identification Xt4/XtDestroyWidget 1
    Problem Summary TSD4W.00151 This test may fail as it is destroying the same widget twice.
    Problem Text
    The segv above results from the second call to XtDestroyWidget as
    per $TET_ROOT/vsw5/tset/Xt4/tdestywid/tdestywid.m:130

    What appears to be happening in our case is ....

    The first call to XtDestroyWidget(labelw_msg) is made.
    As part of the execution of this function labelw_msg is freed.
    tet_infoline() is called next and ends up allocating/writing to
    storage which includes the address of the previously destroyed
    widget. This results in the widget's being_destroyed flag being
    unset which causes the subsequent XtDestroyWidget(labelw_msg)
    to crash.

    Test Output
