            Bug ID: 63385
           Summary: internal compiler error: in pop_binding, at
                    cp/name-lookup.c for implicitly captured variable
                    called closure
           Product: gcc
           Version: 4.8.3
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: kretz at kde dot org

Testcase:

template <typename F> void f(F closure) { auto g = [&]() { return closure; }; }

Compile with 'g++ -std=c++11'. Output with gcc 4.8.3:
internal compiler error: in pop_binding, at cp/name-lookup.c:382
 template <typename F> void f(F closure) { auto g = [=]() { return closure; };
}
                                                                            ^

4.9.x compiles the code fine.
