LI78465: THE TEXT ")" IS UNEXPECTED ERROR

XL C/C++ for Linux Fix Pack 2 (February 2015 Update) for 13.1

APAR status

• Closed as program error.

Error description

• The compiler issues an error message in the utility header file;
  which the client doesn't include directly.
  
  ===== COMPILE COMMAND:
  xlC_r -q32 -qthreaded -qalias=ansi -qlanglvl=extended0x
  -c test.cpp
  
  ===== TESTCASE:
  $ cat test3.cpp
  #include <vector>
  #include <map>
  #include <algorithm>
  
  namespace {
      template <typename PairType>
      struct second_t
      {
          typename PairType::second_type operator()( const
  PairType& p ) const
          {
              return p.second;
          }
      };
  
      template <typename MapType>
      second_t<typename MapType::value_type> second(const MapType
  &m)
      {
          static_cast<void>(m);
          return second_t<typename MapType::value_type>();
      }
  }
  
  int main()
  {
      std::map<int, int> aMap;
      aMap.insert(1, 1);
  
      std::vector<int> seconds;
  
      std::transform(aMap.begin(),
                     aMap.end(),
                     std::back_inserter(seconds),
                     second(aMap));
  }
  $
  
  
  ===== ACTUAL OUTPUT:
  $ xlC_r -q32 -qthreaded -qalias=ansi -qlanglvl=extended0x
  -c test.cpp
  "/usr/vacpp/include/utility", line 96.64: 1540-0063 (S) The
  text ")" is unexpected.

  ===== EXPECTED OUTPUT:
  $ xlC_r -q32 -qthreaded -qalias=ansi -qlanglvl=extended0x -c
  test.cpp
  /opt/IBM/xlC/13.1.0/include/xtree", line 360.32: 1540-0201 (S)
  The "unary *" operator is not allowed for type "int".
  /opt/IBM/xlC/13.1.0/include/xtree", line 358.22: 1540-0700 (I)
  The previous message was produced while processing
  "std::_Tree<std::_Tmap_traits<int,int,std::less<int>,std::alloca
  tor<std::pair<const int,int> >,0> >::insert<int>(int, int)".
  "test.cpp", line 26.9: 1540-0700 (I) The previous message was
  produced while processing "main()".

Local fix

• N/A
  

Problem summary

• USERS AFFECTED:
  All users using -qlanglvl=extended0x with multiple less than
  operator beside identifiers are affected by this issue.
  
  PROBLEM DESCRIPTION:
  VariadicTemplate langlvl was causing some operator 'less than'
  to be registered as arglist inititation.
  

Problem conclusion

• The compiler no longer confuses the 'less than' for arglist
  with -qlanglvl=variadictemplates.
  

Temporary fix
