 Hi,
 
 With this test :
 #include <stdio.h>
 #include <stdlib.h>
 #include <signal.h>
 #include <unistd.h>
 
 
 void
 handler(int signal, siginfo_t *siginfo, void *context)
 {
          int i;
          char *p = (char *)siginfo;
 
          printf("si_pid: %d (%d)\n", siginfo->si_pid, getpid());
          printf("si_uid: %d\n", siginfo->si_uid);
 
          _exit(1);
 }
 
 int
 main(void)
 {
          struct sigaction sa;
 
          sa.sa_sigaction = handler;
          sa.sa_flags = SA_SIGINFO;
          sigemptyset(&sa.sa_mask);
 
          sigaction(SIGABRT, &sa, NULL);
          abort();
          return 0;
 }
 
 I can indeed reproduce the same behaviour with RELENG_8_0 at least.
 
 But it seems this has been fixed by kid@ under CURRENT (SVN rev 199355).
 
 There is a MFC (SVN rev 200729), and therefore I can't reproduce anymore
 this misbehaviour with RELENG_8 as of yesterday.
 
 Could you please confirm your software (RPL/2) work now as expected with
 latest RELENG_8 ?
 
 Thanks,
