    Test Identification Xlib8/XFlushGC 2
    Problem Summary TSD4W.00143 This test may fail on implementations because XGetGCValues() is called with a bad value.
    Problem Text
    This test case [files tset/Xlib8/flushgc/flushgc.m] modifies an allocated GC
    and checks it by calling the function svcFlushGC [line 405]. The check is done
    in the function svcFlushGC within the lines 108 to 125:

    if ((regr_args.l_flags.check) &&
    (errflg == 0) &&
    (stat_status == REGR_NORMAL))
    {
    GC good_defaults;
    unsigned long value_mask;
    XGCValues values;

    value_mask = ( GCLineWidth | GCLineStyle
    | GCCapStyle | GCJoinStyle ) ;
    XGetGCValues(display, good_defaults,
    value_mask, &values);
    check_dec((long)0,
    (long)values.line_width, "line_width");
    check_dec((long)LineSolid,
    (long)values.line_style, "line style");
    }
    XSync(display_arg, 0);

    Within these lines of code the Xlib function XGetGCValues is called
    with the GC parameter good_defaults. But good_defaults is a not initialised
    variable just allocated on the stack. If XGetGCValues is called with
    GC parameter set to gc_id instead, which is the GC passed to the function
    svcFlushGC the created and modified GC is tested and the test passes without
    error. From our point of view this a programming bug in the VSW5 test case.
