#--leak-check=full: "each individual leak will be shown in detail"
#--show-leak-kinds=all: Show all of "definite, indirect, possible, 
#				reachable" leak kinds in the "full" report.
#--track-origins=yes: Favor useful output over speed. This tracks 
#			the origins of uninitialized values, which could be very useful 
#			for memory errors. Consider turning off if Valgrind is unacceptably slow.
