There will be many reasons. What I know is that there will be some "undefined behaviors". This behaviors is not standard c++ which will lead to different outputs with different compilers.

Also, multi-thread programming will lead to different answers, but this seems not your circumstance.

I found some interesting answers in stackoverflow through google. Maybe you can search something you need.
