  .Fn pipe
  function conforms to
  .St -p1003.1-90 .
+ .Sh BUGS
+ At present, EFAULT is not returned by
+ .Fn pipe ,
+ rather, the current implementation does not handle a bad address
+ gracefully.  A core dump as a result of either
+ .Dv SIGSEGV
+ or
+ .Dv SIGBUS
+ can be expected, instead, if a bad address is supplied as the
+ .Fa fildes
+ buffer.  A future implementation of
+ .Fn pipe ,
+ may return EFAULT instead of generating a core dump.
