Details

    Description

      Basically mem_heap_t should poison all not yet allocated and all freed memory. Opposite for MEM_ROOT it's not instrumented at all.

          Looks like it's actually implemented in 5.5. But not in 10.0+ due to merge error. I consider it a result of macro complications and will fix in 10.0 by intruducing MY_ASAN_POISON_MEMORY_REGION() macro.

          I think that we should resolve the merge error differently, by making the InnoDB interface to ASAN and Valgrind in 10.0 more similar to how it is in 5.5.
