Code review comment for lp:~widelands-dev/widelands/fh1-multitexture

Got a compiler warning:

/home/kaputtnik/Quellcode/widelands-repo/fh1-multitexture/src/graphic/text/rendered_text.cc:129:14: Warnung: unused variable »maximum_size« [-Wunused-variable]
    const int maximum_size = kMinimumSizeForTextures;
              ^~~~~~~~~~~~

And some crashes, but i am not sure if they are related to this branch, because trunk crashes also sometimes without a reason. One crash in this branch shows in console:

SaveHandler::save_game() took 659ms
Autosave: save took 660 ms
pure virtual method called
terminate called without an active exception
Abgebrochen (Speicherabzug geschrieben

Will try to get a backtrace...
