cat lazy.c

If you compile that with -Wall -Wextra -pedantic or -WWhatever no warning is emitted and the resulting code calls

..call printf ..

instead of

call __printf_chk .. as it would when is included.

This program contains nothing about __printf_chk, so why do you think there should be a call to it?
