Error description

  • Compiler incorrectly issues spurious warning about passing
    non-POD via ellipsis.
    
    Consider the following example:
    
    $ cat test.cpp
    ////////////////////////////////////////////
    #include <string>
    std::string foo(std::string s, ...) {
      return "";
    }
    
    int main(int argc, char** argv) {
      foo("the nameless are like dust");
    
      return 0;
    }
    ////////////////////////////////////////////
    
    Warning is issued at the compile step:
    
    xlC -o test_program  test.cpp
    "test.cpp", line 8.7: 1540-2924 (W) Cannot pass an argument of
    non-POD class type
    "std::basic_string<char,std::char_traits<char>,std::allocator<ch
    ar> >" through ellipsis.
