From 2392b84fb2f8daf71e70dd13101ec70ff636a3d3 Mon Sep 17 00:00:00 2001 From: Gilad Ben-Yossef Date: Sun, 7 Jan 2018 12:14:34 +0000 Subject: stating: ccree: fix allocation of void sized buf We were allocating buffers using sizeof(*struct->field) where field was type void. Fix it by having a local variable with the real type.
