Re: Bug: ZSH crashes upon receiving SIGINT

[Andrew Janke <janke@xxxxxxxxx>]

Hi folks,

I was able to set up an Arch Linux instance that can consistently 
reproduce this issue. It's on a public-facing server, so if having 
access to work with this directly would help you debug it, send me a 
direct email with a desired username and public SSH key and I'll set you 
up with an account.


To set up a server to reproduce the issue:
Start with a fresh Arch Linux installation, and then:

pacman -Syy
pacman -S zsh arch-install-scripts
mkdir -p /chroots/mini
pacstrap -d -i /chroots/mini base zsh

Then to make the breakage happen:

arch-chroot /chroots/mini /bin/zsh

Wait for the prompt and hit Ctrl-C. It'll immediately produce those 
umount and input error messages.

After you get errors from this, your mount table will be in an unclean 
state and subsequent arch-chroot calls will fail. To clean up manually 
so you can arch-chroot again:

umount /chroots/mini/dev/pts
umount /chroots/mini/dev


Cheers,
Andrew
