Try
debug_on_error (true);
Then execute your print commands. You should get a "debug> " prompt.
Then you can use "dbstack" to show you where the error occurred.
Maybe that will give you some clues about what is happening.

There may be a leak, but that looks small, so it doesn't seem that it
would be enough to cause Octave to use all of your available memory in
just a few calls to print.
