You are right. Personally I always free all memory before falling out of
main().
Although after exiting from main() still lots of code is executed, returing
from main() feels like the end of the program. Any pointer that can be reached
at this point seems for me to be "still reachable".
Altogether I wrote this example only because this is what I expect. I do not
expect that anything is changed to fulfill that expectation.
