zones for each malloc bucket size. The purpose is to isolate different malloc types into hash classes, so that any buffer overruns or use-after-free will usually only affect memory from malloc types in that hash class. This is purely a debugging tool; by varying the hash function and tracking which hash class was corrupted, the intersection of the hash classes from each instance will point to a single malloc type that is being misused. At this point inspection or memguard(9) can be used to catch the offending code. Add MALLOC_DEBUG_MAXZONES=8 to -current GENERIC configuration files. The suggestion to have this on by default came from Kostik Belousov on -arch. This code is based on work by Ron Steinke at Isilon Systems.
