Why doesn't this work?

Are there some obscure rules regarding exceptions and threads that I don't know about? The program crashes when I throw the logic error. 

#include "windows.h"
#include <iostream>
#include <stdexcept>

void foo(void)
 {
  throw std::logic_error("Why does this line crash?!");
 }

DWORD WINAPI threadEntryPoint(LPVOID)
 {
  try
   {
    Sleep(500); // Kill some time. . .
    foo();
   }
  
  catch(const std::exception &error)
   {}
  
  return 0;
 }

int main()
 {
  HANDLE thread[4];
  DWORD id[4];
  
  for(int i=0; i<4; ++i)
   thread=CreateThread(0, 0, &threadEntryPoint, 0, 0, id+i);
  
  WaitForMultipleObjects(4, thread, TRUE, INFINITE);
  
  std::cout << "Done!" << std::endl;
  std::cin.get();
  
  return 0;
 }
Any insight would be appreciated.
Chess is played by three people. Two people play the game; the third provides moral support for the pawns. The object of the game is to kill your opponent by flinging captured pieces at his head. Since the only piece that can be killed is a pawn, the two armies agree to meet in a pawn-infested area (or even a pawn shop) and kill as many pawns as possible in the crossfire. If the game goes on for an hour, one player may legally attempt to gouge out the other

I'm thinking this is compiler specific, so I'm going to add that I'm using GCC 3.4.2. There's probably some switch I need to use or something I need to define.

Okay, I needed to compile with -mthreads. That was simple enough. Well, if anyone else has this problem, now you know the answer.

Well, -mthreads worked well for fixorizing my stand alone executables, But now my dynamically loaded libraries aren't being loaded dynamically. Foobie.

I'll have to look into this tomorrow. Or would that be later today? Blah.
