I managed to duplicate the "Text is read-only" warning with a different program. But if I understand you correctly, if you set comint-prompt-read-only to nil, you of course no longer get the warning, but the duplicate input still does not get deleted. That is the behavior I observe with my program too (the mathematical software package GAP). GAP has a special command line option to get around this when it is called from within Emacs.
I do not know which situations comint-process-echoes was designed to handle, so I do not know whether the behavior I observe is a bug in the comint-process-echoes implementation. I will take a look at the "Text is read-only" warning.
