I don't see those warnings when I build. Or did you add extra compiler flags ? If the latter we should make sure they're included in our default flag set so we don't reintroduce similar flaws in the future.gcc snapshot build a week or two ago on rawhide, but these options aren't new. I always use -Wformat and -Wformat-security. Here's a patch: * acinclude.m4 (minimum): Add -Wformat and -Wformat-security. diff --git a/acinclude.m4 b/acinclude.m4 index 15bb7ff..1c4051d 100644 --- a/acinclude.m4 +++ b/acinclude.m4 @@ -26,7 +26,7 @@ AC_DEFUN([LIBVIRT_COMPILE_WARNINGS],[ try_compiler_flags="" ;; minimum) - try_compiler_flags="-Wall $common_flags" + try_compiler_flags="-Wall -Wformat -Wformat-security $common_flags" ;; yes) try_compiler_flags="-Wall -Wmissing-prototypes $common_flags"
I'm just going to apply this and your other patch, because I always compile with --enable-compile-warnings=error to catch exactly these sorts of regressions / errors, and I wasn't seeing that bug in util.c until you pointed it out.
