Author: Timothy Arceri <tarc...@itsqueeze.com> Date: Fri Aug 25 14:04:19 2017 +1000 disk_cache: assert if a cache entries keys don't match mesa In ef42423e7be9 I enabled the check for release builds however we still want to assert in debug builds in case of collisions or just general bugs with the key building/compare code. Otherwise it will just fail silently effectively disabling the cache.
