can someone explain why this doesn't work?

(the child process just segfaults, even without the printfs)

----- CUT 

#include <stdio.h>
#include <unistd.h>

volatile int t=0;

int main(void){

   pid_t pid;

   if(pid = rfork(RFPROC | RFMEM)){
      printf("(parent)pid = %d\n",pid);
      while(1){
         printf("%d\n",t);
         sleep(1);
      }
   } else {
      printf("doesn't die here...");
      t = 1;
      printf("changed t... ");
      sleep(10000);
   }

   printf("pid = %d about to exit\n",pid);
   return(0);
}
