[issue25717] tempfile.TemporaryFile fails when dir option set to directory residing on host OS mount

[Martin Panter]

Martin Panter added the comment:

This original bug was about fstat() failing for an anonymous file (after the directory entry was removed). But in your situation the file system refuses to unlink the directory entry.

If you think there is something that can be fixed in Python, I suggest open a new bug. But it seems this is working as documented: “Under Unix, the directory entry for the file is removed immediately after the file is created.” In your case, this cannot happen, so you get the error from the OS.
