  g++-4.8.4, Ubuntu 14.04, internal compiler error: in unify, at cp/pt.c

Bug description:
  Hi,
  I' running Ubuntu 14.04.3 LTS and have the package g++4:4.8.2-1ubuntu6  installed.

  When trying to compile the following snippet I get an internal
  compiler error.

  ---

  #include <string>
  #include <iostream>

  template <typename ... Args>
  std::string build_string(std::string fmt, std::initializer_list<Args...> args) {
      for (const auto& arg : args) {
          // use arg to build string
      }

      return "foo";
  }  

  
  int main() {
      build_string("%.2f and %s", {3.14, "Hello"} );
  }

  ---

  The compiler flags were:
  g++ -o bla --std=c++11 bla.cxx 


  The obtained error message is:

  bla.cxx: In function ‘int main()’:
  bla.cxx:17:49: internal compiler error: in unify, at cp/pt.c:17258
       build_string("%.2f and %s", {3.14, "Hello"} );
                                                   ^
