--- Comment #6 from Jason Merrill <jason at gcc dot gnu.org> ---
On gcc-patches (https://gcc.gnu.org/ml/gcc-patches/2019-02/threads.html#01619)
richi pointed out that the testcase is invalid because the undefined functions
we warn about can never be defined, and I agree. And indeed with
-pedantic-errors the warnings become errors, so we reject the testcase at
compile time and never get to LTO.
So another possible fix would be changing the pedwarn in
check_global_declaration to an error.
