    Problem Summary PG4W.00096 This submitter claims the test may fail because of errant XtFree() calls.
    Problem Text

    Test calls XtAppReleaseCacheRefs passing a pointer to memory on
    the stack. This memory is XtFree'ed and the test crashes on the
    next (or future) malloc.
    Test Output
    TEST CASE: XtAppReleaseCacheRefs

    TEST PURPOSE #2
    Assertion XtAppReleaseCacheRefs-2.(A)
    A successful call to void
    XtAppReleaseCacheRefs(app_context, refs) shall call the
    destructor procedure and remove the resource from the
    conversion cache for any conversion entry in refs that
    reaches a conversion count of zero.
    PREP: Initialize toolkit, Open display and Create topLevel root widget
    PREP: Create windows for widgets and map them
    TEST: Register resource converter and destructor
    TEST: Invoke resource converter twice
    TEST: Resource converter was invoked
    TEST: Release the cached resource value
    TEST: Release the cached resource value again
    unexpected signal 11 (SIGSEGV) received

    Review Response
    We recommend this request be refused.

    Our opinion differs. We believe the test is correct.

    We do not believe that this test has the same issue as TIN4W.00008.
    The test code does not make any calls to XtFree(). In addition, the
    reference X code below

    ---------------------------------------------------------------------------
    void XtAppReleaseCacheRefs(app, refs)
    XtAppContext app;
    XtCacheRef *refs;
    {
    register CachePtr *r;
    register CachePtr p;

    LOCK_APP(app);
    LOCK_PROCESS;
    for (r = (CachePtr*)refs; p = *r; r++) {
    if (p->is_refcounted && --(CEXT(p)->ref_count) == 0) {
    FreeCacheRec(app, p, NULL);
    }
    }
    UNLOCK_PROCESS;
    UNLOCK_APP(app);
    }
    ---------------------------------------------------------------------------

    does not make any direct calls to XtFree(). The FreeCacheRec() code
    does call XtFree(), but it is freeing items in the XtCacheRef refs
    linked list, not the refs pointer itself.
