  64. <p>As shown above, describing even a simple C<tt>++</tt> class definition is
  65. accomplished by massively extending the stab format used in C to
  66. describe structure types. However, once the class is defined, C stabs
  67. with no modifications can be used to describe class instances. The
  68. following source:
  69. </p>
  70. <div class="example">
  71. <pre class="example">main () {
  72. baseA AbaseA;
  73. }
  74. </pre></div>
  75. <p>yields the following stab describing the class instance. It looks no
  76. different from a standard C stab describing a local variable.
  77. </p>
