[New-bugs-announce] [issue20764] os.walk recurses down even with dirnames deleted

[Sworddragon]

New submission from Sworddragon:

The following was tested on Linux. In the attachments is the example code and here is my output:

sworddragon at ubuntu:/tmp$ ./test.py
1


I'm deleting the list of directories on every recursion and skipping if I'm directly in /proc (which is theoretically already unneeded). Also the default value for topdown is True and followlinks is False. I have already read the documentation but I'm not seeing any way how the condition could be True so I'm assuming this is a bug.
