this silences warning for uninitialized variable use and safe guards against wrong data used
i do not know what was the original intention of this code but as the warning said, it returned a reference to local data. As it was not really used anywhere, i remove it.
I thought compilers today were smart enough to recognize that there is no return after an assert(0) but apparently this is not so.

Hi, i built it on windows with MSVC and on linux with gcc and clang and i had several compiler warnings.
They are not important but i find it very distracting when i am trying to find my own actual errors so i fixed those.
Or I hope i fixed them, i do not know if you like those fixes.
