Summary:                    utils/refcounter segfaults due to reference of
count1_obj when its NULL
Description: 
I'm not sure if this happens to everyone or just something unique in my
situation.  First time I've played with refcounter.

Line 164 prints an error if count1_obj doesn't exist but then tries to
reference count1_obj->addr which is a guaranteed segfault.

Not sure what the appropriate action is here, in my copy I just removed
the reference so the error message is just printed.

-                               printf("BAD: object %x appears without
previous allocation marker!\n", count1_obj->addr);
+                               printf("BAD: object appears without
previous allocation marker!\n");
