Ar an deichiú lá de mí Méan Fómhair, scríobh Alan Mackenzie: It causes problems in cc-align.el because that’s the first file compiled and the sequence of buffers made current is slightly different for the first file compiled than for later files. I can equally provoke the (new) error message like so: $ /Sources/xemacs-21.5-buffer-warning/src/xemacs -batch -no-site-file -q -f batch-byte-compile cc-engine.el Compiling /tmp/aidan/cc-mode-5.32/cc-engine.el... While compiling toplevel forms in file /tmp/aidan/cc-mode-5.32/cc-engine.el: !! Invalid state (("byte compiling didn't save-excursion appropriately" #<buffer "*Compile-Log*">)) Killing the current buffer is analogous to this: (let ((old-buffer (current-buffer))) (set-buffer (other-buffer old-buffer)) (kill-buffer old-buffer)) and #'other-buffer doesn’t offer any guarantee that it will be particularly predictable, neither in its documentation nor in its implementation. Wrap your #'set-buffers. Right now it throws the error for me if I call M-x byte-compile-file RET; I’m glad it no longer fails silently.
