We have had occasional reports of crashes related to the cons list
before, but I really wonder why you see them so consistently.

E.g. I use ediff too and haven't seen any problems...

What kind of files do you compare with ediff?
Any special character set or encoding in those files?

What does M-x list-processes show ?
