I guess my test case wasn't a correct simplification of
the gnulib test case. Could you please try the following
test case instead? Thanks.
#include <signal.h>
#include <stdio.h>
#include <unistd.h>
static void
handler (int sig)
{
struct sigaction sa;
if (sigaction (SIGABRT, 0, &sa) != 0)
perror ("handler sigaction"), _exit (1);
if (sa.sa_flags & SA_SIGINFO)
{
static char const msg[] = "handler sigaction wrongly reports
SA_SIGINFO\n";
write (STDERR_FILENO, msg, sizeof msg - 1);
_exit (1);
}
if (sa.sa_handler != SIG_DFL)
{
static char const msg[] = "handler sa_handler is not SIG_DFL\n";
write (STDERR_FILENO, msg, sizeof msg - 1);
_exit (1);
}
}
int
main (void)
{
struct sigaction sa;
sa.sa_flags = SA_RESETHAND | SA_NODEFER;
sa.sa_handler = handler;
if (sigemptyset (&sa.sa_mask) != 0)
return perror ("sigemptyset"), 1;
if (sigaction (SIGABRT, &sa, 0) != 0)
return perror ("sigaction"), 1;
if (raise (SIGABRT) != 0)
return perror ("raise"), 1;
return 0;
}
