Thank you for the complete example.

It looks like, after you have changed the prompt, you can set the
local value of comint-prompt-regexp to match it.

More generally, when comint-use-prompt-regexp is nil (which it is by
default), gud.el probably ought not to try and use comint-prompt-regexp.
Instead it should use whatever field properties comint adds.
