# Bug report
Minimal reproducer:
```python
"""
Module doctest
>>> raise_with_note()
Traceback (most recent call last):
...
ValueError: Text
Note
"""
def raise_with_note():
err = ValueError('Text')
err.add_note('Note')
raise err
```
Now, run it, you will get a very strange error:
```
ยป ./python.exe -m doctest ex.py
**********************************************************************
File "/Users/sobolev/Desktop/cpython/ex.py", line 4, in ex
Failed example:
raise_with_note()
Expected:
Traceback (most recent call last):
...
ValueError: Text
Note
Got:
Traceback (most recent call last):
File "/Users/sobolev/Desktop/cpython/Lib/doctest.py", line 1374, in __run
exec(compile(example.source, filename, "single",
File "<doctest ex[0]>", line 1, in <module>
raise_with_note()
File "/Users/sobolev/Desktop/cpython/ex.py", line 14, in raise_with_note
raise err
ValueError: Text
Note
**********************************************************************
1 items had failures:
1 of 1 in ex
***Test Failed*** 1 failures.
```
Things that do not help:
- `IGNORE_EXCEPTION_DETAIL`
- `ELLIPSIS`
- Coping the whole traceback
Related to how exceptions with notes are represented in https://github.com/python/cpython/blob/7237fb578dc9db9dc557759a24d8083425107b91/Lib/doctest.py#L1396
I am working on this issue right now :)
