Wielowątkowość i wyjątki

Otóż mam takie 3 pliczki:

main.cpp

#include <cstdlib>
#include <iostream>
#include "testexception.h"

using namespace std;

int main(int argc, char *argv[])
{
	for (int i=0; i<5; i++){ 
		new testException(i);
	}
    system("PAUSE");
    return EXIT_SUCCESS;
}

////////////testException.cpp///////////////////////////////////////////////////////////////////////////////////////////////
#include "testException.h"
#include <stdio.h>

testException::testException(int index){
	this->index= index;
	createThread();
}

testException::~testException(){
}

bool testException::createThread (){
		par*	this_param = new par;
		this_param->te	= this;
			this->hThread = ::CreateThread(NULL, 0, 
				(unsigned long (__stdcall *)(void *))this->runProcess, 
				(void *)(this_param), 0, &this->hThreadId);
	
		return this->hThread ? true : false;
}

DWORD testException::runProcess (void* Param){
	testException* te= ( ( par*)Param)->te;
	int count=0;
	do{
		try{
			count++;
			printf("Throw %d - %d\n",te->index, count);
			throw 11;
		}catch (int& a){
			printf("Catch %d - %d\n",te->index, a);
		}
		Sleep(50);
	}while (count<400);
	printf("Koniec :%d \n",te->index);
	return 0;
}

Czy ktoś może mi powiedzieć, dlaczego to nie działa? Program przerywa swoje działanie po kilku printfach. ;(

MinGW-GCC [???]

-mthreads
Support thread-safe exception handling on Mingw32. Code that relies on thread-safe exception handling must compile and link all code with the -mthreads option. When compiling, -mthreads defines -D_MT; when linking, it links in a special thread helper library -lmingwthrd which cleans up per thread exception handling data.
