--- Comment #7 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
BTW, I wonder if we shouldn't issue a warning on this testcase, if the vtable
(and virtual method) are in anonymous namespace and aren't defined in the
current CU, they can't be defined anywhere else and thus it is a user error not
to define them (or the class shouldn't be used where the vtable is needed).
At -O0 on the testcase we end up with _ZTVN12_GLOBAL__N_11AE undefined symbol
(that, again, can't be defined anywhere else), so that is at least link time
error, but at -O2 we don't get that.
