...y stores huge amounts of stack traces”. This is in the
sanitizer_common subdirectory and the support is shared by ASAN and
ThreadSanitizer. The StackDepot is essentially an unbounded hash table,
where each StackTrace is assigned a unique id. ASAN stores this id in the
alloc_context_id field in each ChunkHeader (in the redzone preceding each
allocation). Additionally, there is support for symbolizing and printing
StackTrace objects.

The heap profiler needs to track several pieces of information for each
allocation. Given the mapping of 64-bytes to 8-bytes shadow, we can achieve
