--- Comment #2 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, was fixed in GCC 7.1.0. We should include a testcase to make sure it
does not regress again.

The testcase is something like:

// { dg-do compile }
// { dg-options "-O -std=c++11 -g -dA" }
// { dg-final { scan-assembler-not " DW_TAG_const_type" { xfail {
powerpc-ibm-aix* } } } }

int foo(){
        return 2;
}

int main(){
        int (&g)() = foo;
        return 1;
}
