Description Courtney Goeltzenleuchter 2014-02-14 15:49:19 UTC
Saw intermittent segfault running GLBenchmark 3.0's Manhattan test. Narrowed issue down to writing outside the memory bounds of the texture when decompressing ETC2 data. Probably the root cause of bug 71002 (which has a nice repro) as well.

See patch mesa-add-bounds-checking-to-eliminate-buffer-overrun on mesadev for more details.
