--- Comment #6 from Nick Lewycky <nlewycky at google.com> ---
Looks like this one got fixed somewhere along the way:

$ echo 'void (*bar)(void *x) __attribute__((nonnull));
> int main(int argc, char *argv[])
> {
> bar(0);
> return 0;
> }
> ' | clang -x c++ -
<stdin>:5:6: warning: null passed to a callee which requires a non-null
