BUG: ZSH freezes (on history) when systime is wrong

BUG: ZSH freezes (on history) when systime is wrong

Last weekend I had the problem that I could no longer start a terminal/load
a tty, because
zsh was freezing on it's init.

After booting into emergency mode, and setting my shell to bash, I got
control back, and tried to narrow down the issue.
Zero'ing out parts of my config, I narrowed it down to the history
sesttings, in particular: when I changed the path to the hist file, it
loaded (and exited; because after backing up and creating a new histfile,
zsh loaded but froze on exit).

At that point I noticed the system time was messed up (propably by windows
usage).
After syncing, zsh worked fine again with the original history file.

I wonder if the history contained some timestamp in the future, which got
zsh confused.
But in any case, I thought it was a bug worth mentioning.

With regards,

This sounds a lot like an issue (32574) reported back in April against
zsh 5.0.5: http://www.zsh.org/mla/workers/2014/msg00363.html

		Kind regards, Axel

That sounds exactly like what happened. Curious combination of events
leading to failure.
And indeed, as in the previous report: it's nasty, because one cannot open
a terminal to fix it!
I have a minimal system (I wouldn't have been able to delete the lock
manually),
such that I was forced to reboot with emergency as a kernel line
parameter,chroot into my system and open a bash shell in order to fix it.
