## Description

The UNIX editor Vim prior to version 9.1.0678 has a use-after-free error in
argument list handling. When adding a new file to the argument list, this
triggers `Buf\*` autocommands. If in such an autocommand the buffer that was
just opened is closed (including the window where it is shown), this causes
the window structure to be freed which contains a reference to the argument
list that we are actually modifying. Once the autocommands are completed,
the references to the window and argument list are no longer valid and as
such cause an use-after-free. Impact is low since the user must either
intentionally add some unusual autocommands that wipe a buffer during
creation (either manually or by sourcing a malicious plugin), but it will
crash Vim. The issue has been fixed as of Vim patch v9.1.0678.
