Terminate called without an active exception

This is my code :

#include<iostream>
#include<boost/shared_ptr.hpp>
using namespace std;

void func()
{
    cout<<"   func # "<<endl;
    throw;
}

int main()
{

  try
  {
      int x = -1;
      cout<<"   point 1 "<<endl;
      func();
      cout<<"   point 2 "<<endl;
  }
  catch (exception& e)
  {
      cout<<"  exception caught "<<endl;
      //throw;
  }
  cout<<"   point 3 "<<endl;
  return 0;
}

Now, it's giving this result

point 1
func #
terminate called after throwing an instance of in
Abort

But I was expecting this:

point 1
func #
exception caught

What am I missing?
Why is terminate being called like this?
And also, what if I also throw from catch block?
