From 7ab237b025cbb4c25d345604da32e894379c1721 Mon Sep 17 00:00:00 2001 From: Marcin Bukat Date: Thu, 9 Jan 2014 21:37:07 +0100 Subject: buflib: Add crc field protecting buflib cookie integrity This should catch the case of buffer misuse which results in corrupted cookie of next allocation. The check is performed on move_block() so it may be a bit late. There is buflib_check_valid() provided which checks the integrity of all cookies for given context. On DEBUG build with --sdl-thread this check is carried out for core_ctx on every context switch to catch problems earlier.
