just to clarify.
It's not a GCC bug but a valid warning of an exploitable issue:

Those, who don't see any warnings, should try CFLAGS="-Wall -Wformat
-Wno-format-extra-args -Wformat-security -Wformat-nonliteral
-Wformat=2" make

The question now is - why we shouldn't change code to get rid of most
of compiler warnings? Gazzillion of irrelevant warnings might just
hide some more important ones thus I personally would be +1 for
working around most common warnings to make compilation more silent
and thus more easy to spot any new issues.


PS. Markus M - please provide Your CFLAGS as I don't see any warnings
when compiling r.lake with gcc version 4.6.3 (Gentoo 4.6.3 p1.3,
