Stack corruption due to different pointer types

The C programming language allows you to send a float pointer to a function that expects a double pointer, which causes stack corruption. Example code:
When you run it, you will see that the val_f2 is zero (should be 5):

Visual Studio 2015 will only display stack corruption message when you build in debug mode. In release mode, you don't get a message.

If you copy the same code to a cpp file, Visual Studio will use the C++ compiler and it will not build the code, saying that types are incompatible.
