The heap analyzer is a feature of the debugger that provides a
  graphical representation of memory use in real time.  By studying this
  representation, you can identify areas in your application where memory
  usage and performance can be improved.  For example, you might notice
  allocations that are made too often, memory blocks that are too large,
  evidence of fragmentation, or memory leaks.

  After you locate an area of interest, you can request an enlarged, more
  detailed, or altered view.  You can also request additional information
  on the size, contents, or address of the allocations shown.

  After you narrow your interest to an individual allocation, you can
  request traceback information.  The analyzer allows you to correlate
  the traceback entry for an allocation with source code in your
  application program.  By scrolling through the source-code display, you
  can then identify problematic code and decide how to correct it.

  involved in using the heap analyzer.
