            Bug ID: 60314
           Summary: [4.9][C++1y] ICE with decltype(auto) when generating
                    debug information
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: lucdanton at free dot fr

Using trunk (g++-trunk (GCC) 4.9.0 20140222 (experimental)):

$ cat main.cpp 
// fine
// decltype(auto) qux() { return 42; }

struct foo {
    // also ICEs if not static
    static decltype(auto) bar()
    { return 42; }
};

int main()
{
}

$ g++-trunk -std=c++1y main.cpp # Succeeds
$ g++-trunk -std=c++1y main.cpp -g
main.cpp:4:8: internal compiler error: in gen_type_die_with_usage, at
