    Description

      Redzones are poisoned memory between all allocations from memory heaps. It uses more memory but catches buffer overflow and underflow.

      Actually redzones could present if requested size is not a multiply of 8, because allocations size is aligned by 8. Obviously, it's not guaranteed.

      As a bonus string-like and vector-like containers could be instrumented too. See here for example https://github.com/llvm-mirror/libcxx/blob/ab883e8c3b9fb281e5fe064784951c5addd5d11c/include/vector#L846
