Post your C/C++ Questions and Compiler Questions on another site.
I suggest https://cboard.cprogramming.com/forum.php (https://cboard.cprogramming.com/forum.php) for C/C++ Questions.

Edit: The problem is bad code; not an compiler issue. Look up the term compilation unit and what it means in pragma once.

You could also tell me not to initialize global variables in a header file ..
