Ah, I'm sorry, i realize i did forget to mention a crucial piece of the 
puzzle (marked with + below), namely that I have customized a variable 
to have read-only prompts in comint buffers.
Here is the corrected list of steps:

- Start Emacs as `emacs -Q`
+ Configure prompts to be read-only using M-x set-variable RET 
comint-prompt-read-only RET t
- Visit a new Tcl file, example test.tcl
- Enter a Tcl command for testing, say `puts 42`
- Start Tcl process using C-c C-t
- Switch back to test.tcl buffer using C-x o
- Select all text using C-x h
- Try and send it to Tcl process using C-c C-x

This produces the error which I mentioned earlier.

Kind regards,

Alain
