           Summary: [C++0x] Another incomplete type regression with
                    noexcept
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: marc.glisse@normalesup.org


This is another case of noexcept specifications causing instanciations and
resulting in incomplete types (see PR c++/49107 for the first one). Reporting
against C++ instead of libstdc++ like 49107.

#include <utility>
#include <vector>

    typedef Cell_attribute< Refs> X;
    typedef std::vector<X> Y;

struct Combinatorial_map

{
    typedef int*       Dart_handle;
};

int main()
{
    typedef Combinatorial_map<void > Map2;
    Map2();
}
