PM52247: unexpected behavior of the C++ MISRA rule 2_10_4

APAR status

• Closed as program error.

Error description

• MISRA_2_10_4 states that 'A class, union or enum name (including
  qualification, if any) shall be a unique identifier. '
  
  When the source code below is checked for violations for MISRA
  C++ rule MISRA_2_10_4, it reports violations on the statement
  where it is not expected.
  
  namespace {
  
    class AutoCounter {    // compliant MISRA-2-10-4 but a
  violation is raised
    public:
  
      AutoCounter (int x) {};
  
    };
  
  }
  
  
  class AutoCounter2 {    // compliant MISRA-2-10-4 (correct
  behavior)
    public:
  
      AutoCounter2 (int x) {};
  
    };
  
  
  int test_MISTA_2_10_4 () {
  
        AutoCounter2 counter2(3);
  
        AutoCounter counter(3);
  
    return 4;
  
  }
  
  
  We also observed that if the class 'AutoCounter' is taken off
  from the namespace no violation is reported.
  Say like:
  
  class AutoCounter {    // compliant MISRA-2-10-4 but a violation
  is raised
    public:
  
      AutoCounter (int x) {};
  
    };
