Re: SPARC and SA_SIGINFO signal handling

["David S. Miller" <davem@redhat.com>]

You're doing something really wrong, it works perfectly
fine here:

? cat test.c
#include <stdlib.h>
#include <sys/ucontext.h>
#include <signal.h>

void sigsegv_handler (int signo, siginfo_t *info, void *data) {
	if (info != 0)
		exit(1);
	exit(0);
}

int main () {
  int *foo;
  struct sigaction sa;

  sa.sa_sigaction = sigsegv_handler;
  sa.sa_flags = SA_SIGINFO | SA_RESTART;
  sigaction(SIGSEGV, &sa, NULL);

  foo = NULL;
  *foo = 3;
  return 0;
}
? gcc -o test test.c
? ./test
? echo $?
