[New-bugs-announce] [issue42249] Plistlib cannot create binary Plist file larger than 4GiB

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

Due to a typo plistlib uses at most 32 bits for references and offsets. It will fail if try to create a file larger than 4GiB or containing more than 2**32 unique objects (the latter of course implies the former).
