Crash report: CLI autocomplete

[JosephKelly]

Hi there,

• Opened a shell and typed terraform state (with or without a trailing space). Pressing the tab key (->|) causes a crash:

Terraform Version

$ tf -version
Terraform v1.2.1
on linux_amd64

Running from a bash shell on Linux Mint 20.2

$ bash -version
GNU bash, version 5.0.17(1)-release (x86_64-pc-linux-gnu)

Thanks for the report!

Confirmed that this happens in Ubuntu 22.04 (Docker container) with Terraform v1.2.1 installed via apt.

Curiously this does not happen on my main Arch Linux machine.

This is in any case fixed by mitchellh/cli#94. When a new version of mitchellh/cli is tagged, I'll bump the dependency in Terraform.
