Purely an accident.  According to the ISO C standard, it is perfectly OK for
execution of the program to cause demons to fly out of your nose (an ancient
interpretation from news:comp.std.c).

The printf() function is varadic (variable number of arguments).  If you compile
a varadic function without a prototype in scope, the behavior of the program is
undefined.
