Thanks for the pointer.



Unfortunately, this note also happens when compiling testsuite_abi during the

libstdc++ testsuite, that is where I first noticed it.



Here is a C++ test case based on testsuite_abi.cc.



template<typename _CharT>  class basic_string {

      public:

        long unsigned int find(const _CharT* __s, long unsigned int __n) const;

        long unsigned int find(const _CharT* __s) const {

              return this->find(__s, 1);

        }

};

typedef basic_string<char> string;

struct symbol {

     void   init(string& data);

};

void symbol::init(string& data) {

     data.find("FUNC");

}
