  89. *
  90. * 2. Use the clear_malloc function instead of the original malloc.

  99. * where variables are using without to be initialise. To find this
  100. * places, use the fill_malloc function. With this function we want
  101. * to initialize memory to some known bad state. This is quite easily
  102. * spotted in the debugger and will trap to an invalid address.
  103. *
  104. * clear_malloc can be used if you want to set not initialise
  105. * variable to 0.
