Hi,

last week (and now today again, on several terminals after being idle 
since Friday) I noticed that several of my terminals crashed and closed 
when writing `git <tab>` or `ls <tab>`. Managed to capture one such 
crash on video before terminal closed, and it printed "free invalid next 
size (fast)".

Refusing to dump core to tty (use shell redirection or specify --output).

These terminals have been running for ~5 days.
On newly opened terminals, tab completion works fine.

OS: Arch Linux 5.16.13-arch1-1
Package: zsh 5.8.1-1

Have had 5.8-1 on this machine since July, never had any issues. 5.8.1-1 
installed on 16 Feb.


zshrc completion-related stuff:


# The following lines were added by compinstall
zstyle ':completion:*' completer _expand _complete _correct _approximate
zstyle ':completion:*' max-errors 1
zstyle :compinstall filename '/home/johan/.zshrc'

autoload -Uz compinit
compinit
# End of lines added by compinstall

# Enable proper expansion of ..<tab>
zstyle ':completion:*' special-dirs true

setopt HIST_IGNORE_DUPS
setopt HIST_FIND_NO_DUPS


The rest are mostly exports.


Thanks for zsh!

Johan
