  using runtime checks.  The assertions in the check routines spell
  out in more detail the assumptions and invariants underlying the
  algorithms.  The checking is fairly extensive, and will slow down
  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
  set will attempt to check every non-mmapped allocated and free chunk
  in the course of computing the summaries.

ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
  Debugging assertion failures can be nearly impossible if your
  version of the assert macro causes malloc to be called, which will
  lead to a cascade of further failures, blowing the runtime stack.
  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
  which will usually make debugging easier.

MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
  The action to take before "return 0" when malloc fails to be able to
  return memory because there is none available.

HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
  True if this system supports sbrk or an emulation of it.
