* Now you have 3 ways for the malloc function:

* 1. Do not change anything, use the original malloc
*
* 2. Use the clear_malloc function instead of the original malloc.
* In this case you must use the following define:
* #define malloc((_a)) clear_malloc((_a))
*
* 3. Use the fill_malloc function instead of the original malloc.
* In this case you must use the following define:
* #define malloc((_a)) fill_malloc((_a))
*
* We have figured out that there could exist some malloc problems
* where variables are using without to be initialise. To find this
* places, use the fill_malloc function. With this function we want
* to initialize memory to some known bad state. This is quite easily
* spotted in the debugger and will trap to an invalid address.
*
* clear_malloc can be used if you want to set not initialise
* variable to 0.
*
* If you do not want to change the malloc function, to not use one of
* the following macros. Which is the default way.
