[issue39584] multiprocessing.shared_memory: MacOS crashes by running attached Python code

[Davin Potts]

Davin Potts <python at discontinuity.net> added the comment:

My sense is that it would be nice if we can catch this before ftruncate does something nasty.

Where else is ftruncate used in CPython that this could similarly trigger a problem?  How is it handled there (or not)?
