    ada: Bugbox compiling Constrained_Protected_Object'Image
    
    In some cases, a bugbox is generated when compiling an example
    that references X'Image, where X is a constrained object of a
    discriminated protected type.
    
    gcc/ada/
    
            * sem_ch3.adb (Constrain_Corresponding_Record): When copying
            information from the unconstrained record type to a newly
            constructed constrained record subtype, the
            Direct_Primitive_Operations attribute must be copied.
