From a41f2527ae8ae5432b99c88863fbdf2f0b5f04ad Mon Sep 17 00:00:00 2001 From: Bartosz Tomczyk Date: Mon, 30 Jan 2017 14:07:45 +0100 Subject: r600: Fix stack overflow MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Commit 7b5878ee0491e7a93914389a8369cd6752b9757d increased number of outputs to 64, but left output array intact. This caused stack overflow when number of outputs is bigger then 32. Found by ASAN.
