--- Comment #6 from Florian Bruhin <webkit.org at the-compiler.org> ---
If it's a char*, this would be equal to the "naive" bytewise copying below the #ifdef though, right?

If it's more than 20 chars (> s_copyCharsInlineCutOff), memcpy is already used, so if anything used copyChars with the same source/destination, that'd have to be only with strings guaranteed to be shorter, which seems quite a stretch I think?
