Recursive {% include %} crashes silently.

[Brambor]

index.html

{% load static %}

{% include "index.html" %}

view:

def index(request, **kwargs):
	template = loader.get_template('index.html')

	return HttpResponse(template.render({}, request))

url(r'^index$', index) is in urlpatterns in urls.py

When running the server with
python manage.py runserver
and accessing http://localhost:8000/index
The server just stops, not printing anything

cmd line looks like this:

>>>python manage.py runserver
Watching for file changes with StatReloader
Performing system checks...

Django version 3.2.12, using settings 'settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CTRL-BREAK.

>>>

I also tried python manage.py runserver -v 3, which too didn't print anything.

If I have seen a simple "Ran out of memory" Exception or something, it would occur to me that I did include X in X. Without that error message, I wondered, whether the issue is that something is called index and that word is reserved somewhere.

Thanks for the report. On Django 4.0 it crashes with RecursionError: maximum recursion depth exceeded and on Django 3.2 it crashes with:

Fatal Python error: Cannot recover from stack overflow.
Python runtime state: initialized

It seems to have been accidentally improved in 854e9b066850b9b4eb1171966e996322b2c16d27. Unfortunately, Django 3.2 is in extended support and doesn't receive bugfixes anymore (except security issues and data loss bugs).
