bug#15881: 24.3; Args out of range: 1, 2 (trying to comment out second line region)

[n5k2la421i2u0eml]

----------------
i am following the latest git version. start with 'emacs -Q' and open this .c 
file:

#define _GNU_SOURCE
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
...

(#define _GNU_SOURCE is in the first line)
for the first time when i was trying to comment out the second line (region) 
with (M-;) the error 'Args out of range: 1, 2' showed up.
but when i try it again it works.

i tried the latest stable version, same thing happens

Sorry for my poor English!
