-From 497432fd2131967f349e69dc5d259072151cc4b4 Mon Sep 17 00:00:00 2001

-Subject: [PATCH 1/3] checks: Use proper format modifier for size_t
-
-The size of size_t can vary between architectures, so using %ld isn't
-going to work on 32-bit builds. Use the %zu modifier to make sure it is
-always correct.
