--- Comment #3 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
More to the point if do the following casts GCC would have errored out:
(void*)send_message
(void*)&thread_retval
Since you have the cast and in C, void* has an implicit cast to any other
pointer type, GCC does not error out.
I suspect you added those cast to allow the code to be accepted in the first
place and that is wrong.
