/**
 * Here is an example of mem leak I met today. I didn't write the codes, I just help finding the memleak.
 * Of course the real code is much more complicated, I simplify it here.
 *
 * To prove there is memleak, just compile and run:
 * $ gcc a.cpp --std=c++11 -lstdc++ && ./a.out
 *
 * And you will see below:
 * 4 bytes leaked.
