The following sections describe how to use the heap analyzer when
  memory problems are clearly visible in the default Memory Map display.

  Visible problems include allocations that are larger than you expect,
  that repeat numerous times, that increment at each allocation, and that
  could occur in a more efficient way.

  In such cases, your heap analyzer session consists of the following
  steps:

  1.  Examine the Memory Map display.

  2.  Set display characteristics in the Memory Map (optional).

  3.  Request additional information on individual segments (optional).

  4.  Request traceback information on individual segments.

  5.  Correlate traceback entries with source code routines.
