Another oddity to this is if I change the process coding system
interactively by C-x RET p and give 'utf-8 for both values, the
completion will work because the coding is now:

(utf-8 . utf-8-unix)

but doing it in elisp as this:

(add-hook 'gud-mode-hook
          (lambda ()
            (set-buffer-process-coding-system 'utf-8 'utf-8)))


The process coding system is:

(utf-8-unix . utf-8-unix)

different to the interactive changed one.

I have found the exact same cause of the freeze and have been using this

(add-hook 'gud-mode-hook
          (lambda ()
            (set-buffer-process-coding-system 'utf-8-dos 'utf-8)))

I also wish a proper fix is made available.

Best wishes,
