This happens in worg at: https://git.sr.ht/~bzg/worg/tree/ba6cda890f200d428a5d68e819eef15b5306055f/exporters/ox-docstrings.org#L2490
The documentation for lesser blocks[1] states:
> Lines beginning with an asterisk or `#+` must be quoted by a comma (`,*`, `,#+`).
However, the following test document parses as a lesser block despite containing a line starting with an unescaped #+:
```
#+CATEGORY: foo
#+begin_src text
#+CATEGORY: bar
#+end_src
```
which parses as:
```
(org-data
(:standard-properties
[1 1 1 60 60 0 nil org-data nil nil nil 3 60 nil #<buffer *scratch*> nil nil nil]
:path nil :CATEGORY "foo")
(section
(:standard-properties
[1 1 1 60 60 0 nil first-section nil nil nil 1 60 nil #<buffer *scratch*> nil nil #0])
(keyword
(:standard-properties
[1 1 nil nil 17 0 nil top-comment nil nil nil nil nil nil #<buffer *scratch*> nil nil #1]
:key "CATEGORY" :value "foo"))
(src-block
(:standard-properties
[17 17 nil nil 60 0 nil nil nil nil nil nil nil nil #<buffer *scratch*> nil nil #1]
:language "text" :switches nil :parameters nil :number-lines nil :preserve-indent nil :retain-labels t :use-labels t :label-fmt nil :value "#+CATEGORY: bar\n"))))
```
whereas I would expect this to be
```
(section
(keyword :key "CATEGORY" :value "foo")
(paragraph "#+begin_src text")
(keyword :key "CATEGORY" :value "bar")
(paragraph "#+end_src")
)
```
This test document shows that lines with an unescaped "*" do break up the lesser block:
```
* foo
#+begin_src text
* bar
#+end_src
```

You have to quote #+end_src inside source code blocks or #+end_example
in the case of #+begin_example block
#+begin_example
,#+end_example
#+end_example

Escaping #+ lines is optional and mostly necessary to avoid confusing
parser.
For example, one would need to escape
#+CATEGORY: foo
#+begin_src text
,#+end_src
#+end_src
for obvious reasons.
I have clarified the syntax document in
https://git.sr.ht/~bzg/worg/commit/b1d16efc
Hope the new examples explain better what is going on.

Unlike #+ lines, * is _always_ interpreted as a heading. So, it must
always be escaped.
The parser simply removes commas in all the ,* and ,#+ lines.
