It's standard behavior, but have only found it on https://en.cppreference.com/w/cpp/language/cv#Notes The const qualifier used on a declaration of a non-local non-volatile non-template (since C++14) non-inline (since C++17) variable that is not declared extern gives it internal linkage. This is different from C where const file scope variables have external linkage.
