Bug#258740: sigwait and -lpthread.
Package:libc6-dev
version: 2.3.2.ds1-13
When i link the below program with -lpthread I can't kill the
application with SIGTERM. I found that /proc/<pid>/status list some
different SigBlk
#include <stdio.h>
#include <signal.h>
#include <sys/wait.h>
main()
{
sigset_t set;
int sig;
sigemptyset(&set);
sigaddset(&set,SIGCHLD);
sigwait(&set, &sig);
if(sig == SIGCHLD ){
/*
* Removing the zombie(s)
*/
while(wait3(NULL,WNOHANG,NULL) > 0) ;
} else {
printf("Received a signal on which i was not doing a
sigwait \n");
exit(1);
}
}
I am running this on a 2.4 kernel. With 2.6 it seems to work fine. ( I
found that 2.6 strace reports rt_sigtimedwait where as strace with 2.4
reports rt_sigsuspend )
