Did some digging. ediff-exec-process in ediff-diff.el has this: (defun ediff-exec-process (program buffer synch options &rest files) (let ((data (match-data)) ;; If this is a buffer job, we are diffing temporary files ;; produced by Emacs with ediff-coding-system-for-write, so ;; use the same encoding to read the results. (coding-system-for-read (if (string-match "buffer" (symbol-name ediff-job-name)) ediff-coding-system-for-write ediff-coding-system-for-read)) args) In my particular case I was running executing "d E" from pcl-cvs to merge a file. string-match succeeds so coding-system-for-read is set to ediff-coding-system-for-write = emacs-internal. I guess that's the cause of the error. As a hack, I just changed to code to bind coding-system-for-read to ediff-coding-system-for-read. This allows ediff to continue. However, it then gets another error about ediff-default-variant being an undefined variable. Sure enough it is. It seems that ediff-merg.el was not loaded (autoloaded). If I load it manually, then ediff merge works as I expect it too. (So far. I haven't tried to do the merge itself yet.)
