This is is in relation to BUG# 4627
The wait call doesn't wake up when a signal is received.

We tried to use sigaction but the same thing happens.
here is the code we use to test this.


#include <stdio.h>
#include <stdlib.h>
#include <signal.h>
#include <sys/errno.h>

void static fsigint(s)
int s;
{

   printf("signal %d received\n", s);

}


int main(argc, argv)
int argc;
char *argv[];
{
   int pid;
   int status;

   printf("Current process id is %d\n", getpid());

   pid = fork();   if (pid == 0) {

      printf("Forked process id is %d\n", getpid());
      sleep(1000);
      exit(0);
   }

   signal(SIGINT, fsigint);

   while(1)
   {
      errno = 0;
      status = 0;

      printf("ready and waiting...\n");
      pid = wait(&status);

      printf("after wait pid = %d errno = %d\n", pid, errno);

   }
   exit(0);
}
