And you didn't bother to mention the diagnostic? I get
warning: ISO C++ forbids converting a string constant to ‘char*’ [-Wwrite-strings]
And of course with "-pedantic-errors" it becomes a fatal error.
Did you not get a diagnostic? It's not all that interesting to see what
you can get away with by ignoring warnings.

What I typically observe is that skilled programmers pay attention to
warnings and do not attempt to modify string literals.

My quick experiment with MSVC 2017 does not confirm that.
char *s = "ABC";
gives a fatal error in C++. It compiles in C (as expected), but
attempting to modify the literal causes a run-time crash.
