      Your response 
    appears to imply that this change should make it easier to 
    debug the problem.  Since installing this change the problem 
    has not re-occurred.  I took the change out and it occurs 

This is quite puzzling.

    When which-function-mode turns itself off the error which
    the code below implies will be reported is nowhere to be
    found in my *messages* buffer.  I.E.
    "Error in which-func-update: ..."

What is the rest of the message?  The text you left out contained the
only information that we have about the cause of the problem.

    This is the trace I got today, without the above patch installed.
    NOTE that pressing `C' did NOT result in the
    "Error in which-func-update" message being reported!

    * which-func-mode(-1)
      byte-code("???\"?" [info which-func-mode -1 error "Error in 
which-func-update: %s"] 3)
      which-func-update-1(#<window 16 on *Occur-N50S*>)

What was the value of `info'?
