NetBSD riemann 4.0 NetBSD 4.0 (GENERIC.MP) #0: Sun Dec 16 02:23:20 PST 2007  builds@wb29:/home/builds/ab/netbsd-4-0-RELEASE/sparc/200712160005Z-obj/home/builds/ab/netbsd-4-0-RELEASE/src/sys/arch/sparc/compile/GENERIC.MP sparc
>Description:
sigpending doesn't work. "set" argument is not modified when signal is caught.
>How-To-Repeat:
Try to build a simple program with :

          while(sigismember(&set, SIGUSR1) == 0)
            {
                if (sigpending(&set) != 0)
                {
                    exit(0);
                }
            }

Run this code, and send SIGUSR1. 'set' variable is never modified.
