From a1199d679af4103acdc0fdc17ae9c1274733d673 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Fri, 2 Aug 2019 16:52:17 +0100 Subject: ice: fix potential infinite loop The loop counter of a for-loop is a u8 however this is being compared to an int upper bound and this can lead to an infinite loop if the upper bound is greater than 255 since the loop counter will wrap back to zero. Fix this potential issue by making the loop counter an int.
