This happens when index file is larger than SSIZE_T_MAX, i.e. 2^31 in
32bit systems.

This is also 2^31..

Yeah. Something's very wrong. It's as if stat() reports wrong file size
to Dovecot.

837089755 is Thu Jul 11 13:55:55 WEST 1996. That's way wrong.

It's not about dovecot-uidlist, but about newly created
dovecot-uidlist.lock file (which it since deleted).

Something's just completely broken in your install.
