APAR status

• Closed as program error.

Error description

• ===== TESTCASE:
  ===Start of t.cpp=====
  typedef const int TypeCI;
  
  struct X {
    static const int a = 1;
    static TypeCI b = 2; // this should be OK
    static const TypeCI c = 2;
  };
  
  int main(){
    return 0;
  }
  ====End of t.cpp=====
  
  ===== ACTUAL OUTPUT:
  $xlC -c t.cpp
  "t.cpp", line 5.17: 1540-1127 (S) Only static data members with
  const integral or const enumeration type can specify an
  initializer in the class definition.
  
  ===== EXPECTED OUTPUT:
  Should not produce error message.
  

Local fix

• n/a
  

Problem summary

• Users who want to initialize a static
  class datamemberin the definition of that class will
  also need to use the 'const' keyword. The defect was that
  if the 'const' was "hidden" inside a typedef,
  the compiler did not properly detect the 'const'.
  
  The compiler was only checking the top level
  cv-qualifiers to attempt to determine
  whether or not 'const' was specified. If the 'const'
  appeared nested within a typedef, the compiler
  assumed the 'const' was missing, and emitted an
  error message.
  

Problem conclusion

• The compiler was modified to recursively examine any
  typedefs in the datamember initialization if 'const'
  could not be found at the top level.
  

Temporary fix
