zle: not enough argument for -C

[avidseeker]

~/.zshrc:

. ~/.local/share/zsh/plugged/zsh-autosuggestions/zsh-autosuggestions.zsh

IFS=$'\n'

autoload -Uz compinit; compinit

results in

_setup:37: compstate: assignment to invalid subscript range

Uncomment any of the three lines in ~/.zshrc and the problem is gone.

$ZSH_VERSION is 5.9
