Why does my while loop end without giving an error? C++ - c++

Question

I have a project which you can create named pipes in c# or c++ and this program will work as a middle man and simply pass the data on. Used to maintain integrity. Though in one of my while loops when I debug it I step on the while loop then it will cancel the steps and not process the while loop. It reaches line 107 of this code. If you need more of my files I will be happy to post them if needed.
