Microsoft c++ optimizing compiler has stopped working

I am trying to define a template member function in a class, and MSVC crashes everytime I try to build this code. I am not sure if this is a bug in Visual Studio 2008. Here is a minimal example.

testTemp.h header file:

#pragma once
#include <vector>
#include <iostream>
class testTemp
{
public:
    testTemp(void);
    ~testTemp(void);
    template<typename T>
    std::vector<T> m_vMonitorVec;
    int MonitorSignal(T x, std::vector<T> vec, int len);
};

and here is testTemp.cpp:

  #include "StdAfx.h"
    #include "testTemp.h"

    testTemp::testTemp(void)
    {
    }

    testTemp::~testTemp(void)
    {
    }
    template<typename T>
    int testTemp::MonitorSignal(T inp, std::vector<T> monVec, int len)
    {

        return 0;
    }

and stdafx.h is:

#pragma once

#include "targetver.h"

#include <stdio.h>
#include <tchar.h>

I am running this in MSVC 2008, whenever I try to build this code, I get the following crash: enter image description here

Template variables are new in c++14. VS2008 certainly doesn't implement them.

template <typename T> std::vector<T> m_vMonitorVec;

should likely be

template <typename T>
class testTemp {
  public:
    testTemp(void) { }
    ~testTemp(void) { }
    int MonitorSignal(T x, std::vector<T> const& vec, int len) {
        return 0; 
    }
  private:
    std::vector<T> m_vMonitorVec;
};

I suggested inline implementation because of this: Why can templates only be implemented in the header file?

PS You could report a compiler bug but they won't fix that old version.
