This is C locale on a 32-bit machine, so you'll likely be seeing the same
complaint in already-online buildfarm members.
Note that size_t is definitely not int64 on this machine, so it looks to
me like your int64-ectomy was incomplete. Those message lengths should
be impossible no matter what on this hardware.
