From 3c676ecee839e6b0a1e5c5d4b3524edcb0bd2a42 Mon Sep 17 00:00:00 2001 From: Tom Sepez Date: Tue, 10 Mar 2015 15:23:02 -0700 Subject: Kill remaining sprintfs I thought I had done this already, apart from the third-party libraries, but there were a couple remaining (the third-party libraries will still call this, they should be tweaked upstream as needed).
