[New-bugs-announce] [issue29079] pathlib.resolve() causes infinite loop on Windows

[Georg Mischler]

New submission from Georg Mischler:

When pathlib.resolve() is invoked on Windows(10) with an absolute path including a non-existing drive, it gets caught in an infinite loop.

To reproduce:
Select a drive letter that doesn't exist on the system (in my case H:).
Run the following line of code:
    pathlib.Path('h:\\').resolve()

Expected result:
returns the input string unchanged.

Actual result:
pathlib.resolve() ends up in an infinite loop, repeatedly calling _getfinalpathname() on the same string.
