From 41af05154abe136938bcfb5f26c969933784bbef Mon Sep 17 00:00:00 2001 From: Deepika Bhavnani Date: Thu, 15 Aug 2019 00:56:46 +0300 Subject: [PATCH] Coverity fix: Remove GGC ignore -Warray-bounds GCC diagnostics were added to ignore array boundaries, instead of ignoring GCC warning current code will check for array boundaries and perform and array update only for valid elements.
