The hidden point is that every other system I've seen that provides
what it calls a traceback does so by printing the most recent call
context first.

As for your question:  Which way a stack grows in memory depends on
the implementation.  I've used machines on which stacks grow from low
addresses toward high addresses, and other machines on which stacks
grow in the opposite directions.  I've even used machines on which
stacks are not contiguous, so the question is meaningless.
