This warning message appears when I compile.
I don't know what string arg does but the warning sign worries me.
not a blocker so far.
@kevin7shlee Thank you for pointing out. It is safe to ignore this message (FETCH_ARG macro ensures arg to be initialized, otherwise it will die) but it is always better to get rid of warnings.
#18: got rid of (incorrect) uninitialization warning on some compilers.
