Repro steps:
- create a "base.html"
- create a "child.html" that inherits from base.html with `{% extends %}`
put one of the following lines child.html:
`{% url 'nonexistent' %}`
`{% include 'nonexistent.html' %}`
Expected: the yellow error page's "template debug" context should
highlight the offending line, as it does when you have a
TemplateSyntaxError during compilation.
Actual: the error page incorrectly blames base.html, and says the error is
at line 0:
"Error during template rendering
In template ...\base.html, error at line 0"
It then shows the first 10 lines of base.html, but of course there is no
error there.
I think this is caused by `django.template.base.Node.render_annotated`,
specifically this line:
`e.template_debug = context.render_context.template.get_exception_info(e,
self.token)`
It seems fixed if I change it to:
`e.template_debug = context.template.get_exception_info(e, self.token)`
(I got the idea because I saw `context.template` referenced on the
previous line.)
You can run the attached project which reproduces the issue (run server
and open to /).
