Sorry, can you spell that out for me?  You're saying that the behavior I'm
seeing is because I'm using malloc.h for the definition of malloc(), rather
than stdlib.h?  malloc.h's definition of malloc has __attribute__((malloc)), so
that allows gcc to perform the optimization even when -fno-builtin in thrown?
