Once upon a time (that would be on the order of about a year ago) I found something that looked like a library or compiler bug that got triggered in hylafax. I belive it resulted in FD_ISSET returning true when the fd was, in fact, not set. Compiling without optimization cured it (which has be believe that it was, or possibly still is as you message seems to imply, a compiler bug).
