 The simple attached file reproduces the error.  It should be built with

 g++-mp-4.7 -std=c++11 test.cpp

 it produces the following linking error:

 {{{
 Undefined symbols for architecture x86_64:
   "std::regex_token_iterator<__gnu_cxx::__normal_iterator<char const*,
 std::basic_string<char, std::char_traits<char>, std::allocator<char> > >,
 char, std::regex_traits<char>
 >::regex_token_iterator(__gnu_cxx::__normal_iterator<char const*,
 std::basic_string<char, std::char_traits<char>, std::allocator<char> > >,
 __gnu_cxx::__normal_iterator<char const*, std::basic_string<char,

 from:
       _main in cccDMjnE.o
 ld: symbol(s) not found for architecture x86_64
 collect2: error: ld returned 1 exit status
 }}}

 The problem does not appear under the system's default clang++ compiler.
 The regex symbols are part of the standard library and should be present
 and properly linked with the test code.
