The following program is stuck in pause(3) forever. I have reproduced the bug in
5.0-RELEASE, but 4.7-STABLE behaves as expected: the child resumes upon
receiving SIGCONT.
#include <err.h>
#include <signal.h>
#include <sys/time.h>
#include <sys/resource.h>
static void
cont_handler()
{ ; }
int main()
{
int child, status;
if (signal(SIGCONT, cont_handler) == SIG_ERR)
err(1, "signal()");
if ((child = fork()) == 0) {
pause();
exit(0);
} else if (child == -1)
err(1, "fork()");
printf("sleeping 3s\n");
sleep(3);
if (kill(child, SIGCONT) == -1)
err(1, "kill()");
printf("waiting\n");
if ((child = wait(status)) == -1)
err(1, "wait()");
printf("done\n");
return (0);
}
Cheers.
