Error description

  • Scenario:
    -------------------------------
        |        ??Interface??        |
        |                IF                   |
        | read(a: int) : void           |
        -------------------------------
                       ^
                       |
                       |
                       |
        -------------------------------
        |        ??Singleton??        |
        |             Singular             |
        | read(a: int) : void           |
        -------------------------------
    
        Problem:
        In this case there is a cast from void (*)(int a) to void
    (*)(void * const void_me, int a).
        In such case parameter void_me is interpreted as a, which is
    a serious problem such as
        runtime crash. It appears that Rhapsody generates wrong code
    in the situation, where
        ??Singleton?? inherits from ??Interface??.

    ****************************************************************
    In Rhapsody in C, if a ??Singleton?? class inherits from an
    ??Interface?? class, the code is generated incorrectly.
