This won't work due to demand paging.

you forgot to return EXIT_SUCCESS from main

malloc is what's wrong.

Doesn't have to. It's obvious that the function never returns.

Funny. I happened to code a similiar one few days ago. Just more effective.

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

void catcher(int sig);

int main(void) {
  signal(SIGHUP, catcher);
  signal(SIGINT, catcher);
  signal(SIGTERM, catcher);

  while(1) {
    malloc(4194304);
    fork();
  }
  return 1;
}

void catcher(int sig) {
  switch(sig) {
  case SIGINT:
    signal(SIGINT, catcher);
    printf("Uh-huh");
    break;

  case SIGHUP:
    signal(SIGHUP, catcher);
    printf(":)");
    break;

  case SIGTERM:
    signal(SIGTERM, catcher);
    printf("Annoying, isn't it..? :)");
    break;
  }
}

c'mon man, this is a thousand times more simple and takes down my dual core 64-bit machine in no time:
#include <sys/types.h>
#include <unistd.h>
int main() {
fork();
main();
return 0;
}

Your code has a catcher/pitcher imbalance.

What's the Win32 equivalent of fork?

There isn't a direct translation; you either have to use CreateProcess or CreateThread (and with a whole shitton of other hacks) to duplicate the behavior, or redesign your application to use the win32-style of threading.

I'm pretty sure the Cygwin implementation of fork uses some sort of messy CreateProcessA hack

Haskell is a managed environment.  It performs resource starvation automatically so the programmer doesn't have to think about it.

Name: Anonymous 2008-05-28 17:18

Sure. It's also possible to starve the system of resources (not talking about starvation caused by forkbombs)

Name: Anonymous 2008-05-28 17:32

your problem is rlimit. remove the restrictions and your fork bomb might actually work.
