            Bug ID: 61122
           Summary: too many initializers
           Product: gcc
           Version: 4.7.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: f.heckenbach@fh-soft.de

g++ says "too many initializers" for an array of vectors with initializers, but
only within a struct.

Not sure if it should work (I don't see why not), but it seems inconsistent
that it only fails within a struct. Also, the error message is misleading ("too
many initializers" even for an empty brace-list).

#include <vector>

std::vector <int> a1[] { { } };
std::vector <int> a2[] { { 1, 2, 3 } };
std::vector <int> a3[] { std::vector <int> () };
std::vector <int> a4[] { std::vector <int> (1) };

struct s
{
  std::vector <int> b1[] { { } };
  std::vector <int> b2[] { { 1, 2, 3 } };
  std::vector <int> b3[] { std::vector <int> () };
  std::vector <int> b4[] { std::vector <int> (1) };
};
