Description Matthias Klose 2014-05-03 16:28:35 UTC 
4.7 rejects this without an ICE, the ICE is seen on 4.8, 4.9 branches and trunk.

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

$ g++-4.7 -Wall -std=gnu++0x tst.cc 
tst.cc:5:3: error: 'std::array<int, 1ul>' has no non-static data member named 'i'

$ g++-4.8 -Wall -std=gnu++0x tst.cc 
tst.cc:5:3: internal compiler error: in lookup_field_1, at cp/search.c:384
   };
