- Check bytes 
                  		  
               
-  Check this to prepend and append check bytes to each memory allocation. 
                  			 
                   Equivalent tunable: 
                     				memory_strategy with check bytes set 
                     			 
                   
- Check the last ... free memory blocks 
                  		  
               
- Specify the number of freed memory blocks to monitor for subsequent corruption.

- Reuse freed memory 
                  		  
               
- Check this if you want to allow freed memory being monitored for corruption to be used to satisfy allocation requests.

- Compatibility 
                  		  
               
- Check this to maintain compatibility with previous versions of the run-time system in the way it handles memory allocations.

- Validate all memory when allocating and freeing 
                  		  
               
- Check this to validate memory each time an allocation or free operation is performed.
