And if I disable by hand the real_isfinite (ra) check in do_mpfr_arg1 I even get 0. And I also checked what happens for sin(Inf) in that case: a -nan as before the hack. Then which is at this point a safe way to proceed? Get in touch with the mpfr people, ask if simplifying infinities has known issues? Tentatively remove the real_isfinite checks from one of the do_mpfr_arg? functions at a time, or even one mathematical function at a time?
