--- Comment #4 from Warner Losh <imp@FreeBSD.org> ---
This awk program is incorrect (the printf uses the input line, but doesn't have
enough args).
awk properly detects this now and does not segfault, but issues the following
diagnostic:
awk: not enough args in printf(%*)
 input record number 1, file conf
 source line number 1
