Warning with `require_file`

[htv04]

I'm currently using Lua 5.1 (LuaJIT). When using the require_file function, I'm getting this error:

(More "inlined from" statements above this but they're not important)
    inlined from 'sol::optional<sol::basic_object<sol::basic_reference<false> > > sol::state_view::is_loaded_package(const std::string&)' at sol/state_view.hpp:50:82:

Looking at the traceback, I found this line: https://github.com/ThePhD/sol2/blob/4de99c5b41b64b7e654bf8e48b177e8414a756b7/include/sol/state_view.hpp#L50

It seems that making these two strings the same length (which would cause issues for Lua though) fixes the warning, so could the error be related to string comparison somehow?
