+ * Description :  malloc wrapper that either succeeds or causes
+ *                program termination.
+ *
+ *                Useful in situations were the buffer size is "small"
+ *                and malloc() failures couldn't be handled better
+ *                anyway. In case of debug builds, failures trigger
+ *                an assert().
+ *
+ * Parameters  :
+ *          1  :  buffer_size = Size of the space to allocate
+ *
+ * Returns     :  Pointer to newly malloc'd memory
+ *
