Not sure what "inplace" means, but it sounds like it runs afoul of: If copying takes place between objects that overlap, the behavior is undefined. and thus it is fair to alert on it. See: https://pubs.opengroup.org/onlinepubs/9699919799/functions/strcpy.html and there is similar language in our man page.
