In this program, We are giving a location to two variables in the program, So it is arising an exception.
Output:
$ g++ free3.cpp
$ a.out
X::operator new(size_t)
X::operator new(size_t, 0)
X::operator new(size_t, 1)
X::operator new(size_t, 2)
10000
10001
10002
X::operator new(size_t, 0)
Error: buffer location occupied
