What is wrong with this code?

I was reading some blogs this week and find an interesting story related to references in C++ (and as it has some time that I don't work/post about C++) so I decided to post about it.

Take a look in the code and try to answer the following questions below:

#include "stdafx.h"
#include "stdio.h"

class SimpleClass
{
public:
SimpleClass(int n)
{
   value = n;
}

void FirstMethod(TCHAR* str)
{
  wprintf(str);
}

void SecondMethod()
{
  wprintf(L"Value: %d", value);
}

private:
int value;
};

void Test(SimpleClass &ref, int i)
{
switch(i)
{
  case 1:
     ref.FirstMethod(L"Hello world\r\n");
     break;

  case 2:
     ref.SecondMethod();
     break;
}
}

int _tmain(int argc, _TCHAR* argv[])
{
SimpleClass *p = 0;

Test(*p, 1);
Test(*p, 2);

return 0;
}

• Will it compile? run?
• What would be the outcome from Test being called in line 39?
• What about line 40?
• Is there any other issues?
  

(PS: VS 2008 compiled it with no warnings....)
