@ -1329,7 +1329,7 @@ Setting this flag for a signal other than @code{SIGCHLD} has no effect.
If this flag is set for a particular signal number, the system uses the
signal stack when delivering that kind of signal. @xref{Signal Stack}.
If a signal with this flag arrives and you have not set a signal stack,
the system terminates the program with @code{SIGILL}.
the normal user stack is used instead, as if the flag had not been set.
