Title:
  internal compiler error with std::array designated initialization

Bug description:
  The following code fails to compile with g++-4.8:

    #include <array>
    const int i = 0;
    std::array<int, 1> bar = {
      [i] = 0
    };

  I have since learned that designated initialization is not supported
  in (GNU) C++.  In that case I would have expected a syntax error.

  This is the compilation command and its output:

    $ g++-4.8 -Wall -std=gnu++11 main.cpp
    main.cpp:5:1: internal compiler error: in lookup_field_1, at cp/search.c:384                 
     };
