Ah size_t again. :) Sounds like it should be %zu for obj->base.size. 
Interestingly this warning did not trigger on my machine.

Would you prefer a fixup patch, a resend of the offender, or manual 
maintainer intervention in git history? (In the last option note there 
are two instances to be fixed up, line 2748 and 2763.)
