--- Comment #3 from Richard Smith <richard-llvm at metafoo.co.uk> ---
Fixed in r199782. For compatibility with GCC and IOCCC entries, we still
silently accept this outside -pedantic mode. With -pedantic-errors, we produce:

<stdin>:1:25: error: ISO C++ does not allow 'main' to be used by a program
[-Werror,-Wmain]
int main() { auto *x = &main; x(); }
                        ^
