I have written a program in vc++ that has different behavior in various case as below.
When I run it by F5 it works properly in release mode.
When I run it by ctrl + F5 it crashes when I start to send data to the program.
Outside of visual studio it crashes immediately.
I don't know how to find the bug. Any idea on what is different between these cases?

Run mode# In addition to debugging a program, VS Code supports running the program. The Debug: Run (Start Without Debugging) action is triggered with Ctrl+F5 and uses the currently selected launch configuration.
F5 is used to start your project in debug mode and Ctrl-F5 is used to start your project without debug mode.
In the simplest case, to build and run an open project in Visual Studio: Press F5, choose Debug > Start with debugging from the Visual Studio menu, or select the green Start arrow and project name on the Visual Studio toolbar.
In Solution Explorer, right-click the project and choose Properties. In the side pane, choose Build (or Compile in Visual Basic). In the Configuration list at the top, choose Debug or Release. Select the Advanced button (or the Advanced Compile Options button in Visual Basic).
Running ctrl + F5 will run the application without debugger. (http://msdn.microsoft.com/en-US/library/8b59xk0f(v=vs.90).aspx) This is not the same as running in release mode.
You can run your application in debug mode but without debugger. It sounds stupid but is for example helpful if you want to stop the console from closing on exit. (How to stop console from closing on exit?)

You need to understand the difference between running an application in debug mode and release mode. F5 will generally help you to debug the application and ctrl + F5 will execute the application. There might be some issues in release mode that makes your vs to crash. Read this to get an understanding.
