    Test Identification Xt13/XtMalloc 1
    Problem Summary TSD4W.00154 These tests may fail as they allocate all available memory and then use TET calls which want to do a malloc.
    Problem Text
    Each of the above tests (XtMalloc-1,2 XtRealloc-3,4,6 XtFree-1)
    fails in the same way ...

    The tests check the max. amount of memory available
    max_limit = mem_limit();

    Subsequently each test allocates max_limit bytes.
    Having checked whatever needs to be checked each test
    proceeds to attempt to free the allocated storage ...

    tet_infoline("CLEANUP: Free memory");
    XtFree(ptr);

    Unfortunately, tet_infoline tries to allocate some storage
    (see tet_bufchk()) even though we've used it all up as
    part of the test.

    The tests pass if the tet_infoline() calls before XtFree()
    are removed!

    Review Recommendation No Resolution Given
    Review Response
    This strikes us a situation where TET is being needless intrusive into
    the operation of a test. However the tests can be simply redesigned to
    work around this without impacting their testing of the assertions. We thus
    recommend a Test Suite Deficiency waiver be granted.

    Review Type SA Review

    Review Resolution Test Suite Deficiency (TSD)
    Review Conclusion
    This is an agreed Test Suite Deficiency.
