[issue25973] Segmentation fault with nonlocal and two underscores

[Nick Coghlan]

Nick Coghlan added the comment:

And as some additional background as to why segmentation faults provoked by Python code aren't currently considered a security bug: since CPython doesn't include a security sandbox, we're already relying entirely on the OS to provide process isolation.

That OS level security boundary isn't affected by whether the code is running "normally", or in a modified state following a deliberately triggered segmentation fault.
