We've seen some reports of such a problem and I've experienced it as well.
I can't reproduce it, but I have the impression that it's timing related.
In my case, the *vc-diff* buffer is shown in a separate frame, and if that
frame is visible when I hit C-x v = the command normally suceeds, whereas if
the frame needs to be deiconified (or worse, created) as part of the C-x v =
command, then the risk seems to be higher that I get "No differences".
I've never experienced the "Proces killed" problem, OTOH.

My impression until now was that if some X window event comes in just at the
wrong time, Emacs would notice that the cvs (or tla in my case) process
exited without reading all the pending output from that process.
Whether that's really what's happening or not, I don't know.

This was all on GNU/Linux systems.
