Remember to cover the basics, that is, what you expected to happen and
what in fact did happen. You don't know how to make a good report? See

Your bug report will be posted to the Org mailing list.
This bug is a bit hard to formulate. Have a look at the following
org-file. Even though it's big, it's almost an MWE:
```
# -*- mode: org; -*-
* Test

:header-args::cache yes :noweb yes
:END:
#+name: empty
#+begin_quote
#+end_quote

printf "%s\n%s" "Test string" "Test string2"
#+end_src

```
You can see that the patch gives two different results for an identical body.
The difference really is in: ":results output code"
This is a bit hard to reproduce, because it also seems to depend on
whether the block was cached, but I find it hard to formulate how
exactly.
In any case, the desired behaviour for me seems to be: take both results from
cache, if they are available, and run the comparison block. If the
cache is outdated, run each outdated block, update the cache, and feed
the cache results into the comparison block.
At the moment org doesn't seem to be updating the cache.
I can imagine thought that if the block output is considered "code",
someone may feel inclined to run the code instead of feeding it verbatim.
