Yeah, gcc is doing weird things here : (
It is kinda sad that same flag does different things with gcc and clang.

So -fno-builtin-stpcpy is not ideal solution then.. gcc may implement this opt

So I (we?) think there is something weird in gcc frontends.

In this case or generally? General bug example:
