I think the five numbers come from four memory allocations before
example() is called. Looking at the code in src/main/memory.c, it
prints newline only when the call stack is not empty.
I don't see why this is done, and I may well be the person who did it
(I don't have svn on this computer to check), but it is clearly
deliberate.
