PH36254: XLCLANG++ CANNOT APPLY __PTR32 QUALIFIER OVER TYPEDEF

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• When compiling code with the xlclang++ invocation, the usage of
  a __ptr32 type qualifier on a typedef of a valid pointer type
  causes an unexpected compile error.
  
  
  
     === TEST CASE ===
  
  #include <stdlib.h>
  #include <stdio.h>
  typedef char * MYTYPE;
  struct myStruct {
    char * __ptr32 ex1;
    MYTYPE __ptr32 ex2;
  };
  
  int main(int argc, char* argv[])
  {
  
  return 0;
  }
  
  
  $ xlclang++ apar.cpp
  ./apar.cpp:6:10: error: '__ptr32' attribute only applies to
  pointer arguments
    MYTYPE __ptr32 ex2;
           ^
  1 error generated.
  Error while processing ./apar.cpp.
  CCN0793(I) Compilation failed for file ./apar.cpp.  Object file
  not created.

Local fix

• Do not use the qualifier on typedefs
