Rational Rhapsody 8.0

APAR status

• Closed as program error.

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.
