Bug report

Bug description:

-X showrefcount should “output the total reference count and number of used memory blocks [...] after each statement in the interactive interpreter. This only works on debug builds.”

This works with PYTHON_BASIC_REPL=1, but with the new REPL the totals are only shown at exit.

CPython versions tested on:

3.13, 3.14, CPython main branch

Operating systems tested on:

Linux
