Order of evaluation of C++ function arguments is not defined, and if
lua_rawlen() was called before lua_tostring() then it would return 0
(because the value was still a number) and an empty string would be
passed.
The same issue affects std::string_view too, but that's not been in
a release yet.
The new testcases fail without the fix with GCC 12.2 on x86-64 Linux.
