[issue38638] Backtrace of exit phase of context managers
New submission from Alexander Kurakin :
class CM:
def __init__(self):
pass
def __enter__(self):
return self
def __exit__(self, exc_type, exc_val, exc_tb):
raise RuntimeError()
if __name__ == '__main__':
with CM() as cm:
print('Hello')
$ python3 cm.py
Hello
Traceback (most recent call last):
File "cm.py", line 14, in
print('Hello') # <--
File "cm.py", line 10, in __exit__
raise RuntimeError()
RuntimeError
Is it correct that print presents in backtrace? Well it's the last line but...
Thanks.

[issue38042] Crash on double list(lxml.etree.iterparse(f))
Alexander Kurakin added the comment: Ok, thanks! Good that I was too lazy to open bug in June because our colleague did it better then me :) Seems like the fix doesn't present in current 3.7 version (3.7.4). Will try in 3.7.5 and will close UPD: Oh, closed? Ok. But *no*, it's not fixed in current 3.7 version (in master - yes). I wrote: 3.7.4. Let's check each other instead of... Sorry.

[issue38042] Crash on double list(lxml.etree.iterparse(f))
Alexander Kurakin added the comment: Yes, I do. Please read all. 1) According to https://bugs.launchpad.net/lxml/+bug/1833050 (by lxml author's opinion) it's not a lxml bug. 2) I wouldn't said that but according to backtrace we have crash at Python-time. 3) Moreover crash existence depends on Python version!
