From a0a0a909f21acfcddaab603079ba98266e8daf0e Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 4 Jan 2012 15:45:49 -0800 Subject: [PATCH] i965: Fix infinite loop regression in intel_miptree_all_slices_resolve. Commit 0ed11e333147e280208d9d0b3ff3f39970547643 fixed a "use after free" bug by getting the next pointer before deleting the current node. Unfortunately, it also made "next" never get updated if i->need != need. Fixes infinite loops in piglit tests fbo-depth-array and fbo-depthtex.
