>Description:
Calling s.replace(pos, num_chars, s) for a string s may not work
properly if the string already has sufficient capacity for the result.
>How-To-Repeat:
The following test program prints "ABABAB". The correct output is
"ABABCD".

#include <iostream>
#include <string>

using namespace std;

int main()
{
	string s("ABCD");
	s.reserve(10);
	s.replace(2, 2, s);
	cout << s << endl;
	return 0;
}
