Passing By Reference then Deleting the Passed Object

[Yadrif]

Why does the following code not break after delete bar? It seems like the object foo would have a reference to a deleted object and crash in printBar(). Is bar not really gone after the "delete bar" line?

#include <cstdlib>
#include <iostream>
#include <string>

using namespace std;

class Bar
{
public:
    Bar() {}
    void print() {
        cerr << "Bar::print(), Hey there!!!!" << endl;
    }

private:

};

class Foo
{
public:
    Foo(Bar& b) : myBar(b) {}

    void printBar() {
        myBar.print();
    }

private:
    Bar& myBar;
};


int main(int argc, char *argv[])
{

    Bar* bar = new Bar();
    Foo* foo = new Foo(*bar);

    delete bar;
    bar->print();
    
    for (int i = 0; i < 10; ++i) {
        foo->printBar();
    }

    system("PAUSE");
    return EXIT_SUCCESS;
}

I tried searching but all search results turn up more general information about references.

Thanks.
