    Certification Program The Open Brand certification program
    Test Suite VSW version 5.0.2
    Test Identification Xlib11/PropertyNotify 1
    Problem Summary MSF4W.00026 Implementation expects 32-bit data to be 64-bit aligned in 64-bit compilation environment.
    Problem Text
    In the testcode a call is made to XChangeProperty as follows:

    XChangeProperty(display, w, atom, XA_INTEGER, 32, PropModeReplace,
    (unsigned char *)&data, 1);

    Where data is declared as an int:

    int data = 42;

    In our Xserver XChangeProperty treats the value passed in data to be a
    long. This is fine in the 32 bit Xserver as sizeof(int) is equal to
    sizeof(long). However in our 64 bit Xserver sizeof(long) does not
    sizeof(int) and this causes the test program to crash.

    We intend to fix this problem, but it requires a large number of
    changes to our Xserver and we are near to the products ship date so a
    major change to the Xserver is not feasible. We are applying for a
    Minor System Fault waiver to allow us to achieve branding for this
    release on the understanding that this problem will be fixed in the
    next release.
