Thread: Access violation error

I am trying to write a getter function from my class, which would return a part of my member variable vector<short>:

Code:

const vector<short> Input::getOneRow(int index) const
{
	try
	{
		return values.at(index);
	}
	catch(const out_of_range &e)
	{
		cerr << "Out of range " << endl;
	}
}

And I try to test it with an out of range value for int index:

Code:

int main()
{
	/* ... declare myClass ... */

	vector<short> test2 = myClass.getOneRow(555); 
}

What happens is that the exception is caught, the error message is printed, but then when my program crashes with some unknown error. Why? What happens?
