I am not sure how to verify that.  

I renamed the comint.elc and then byte-compiled comint.el (I did this because
the .elc header said it was compiled with emacs-21.1).  This did not help.

If I eval the defun, ^C^C works.
If I run esc-: (comint-interrupt-subjob), the routine works.
Just not if I run it via ^C^C via the normal load etc.

If you can guide me a bit, I'll try to verify it...

Not good at this, but I'll give it a try...
