How can I find out what type the compiler deduced when using the auto keyword?

Answer 1

The type deduced by the compiler is in the error message:

/usr/include/c++/4.8.2/ostream:602:5: error:   initializing argument 1 of ‘std::basic_ostream<_CharT, _Traits>& std::operator<<(std::basic_ostream<_CharT, _Traits>&&, const _Tp&) [with _CharT = char; _Traits = std::char_traits;
 _Tp = std::chrono::time_point > >]’
  ^^   <-------- the long type name --------------------------------------------------------------------------------------->

It's a complicated type name but it is there in the error message.
