29.3; Run time error in `dabbrev-completion' |
|
Date: |
Tue, 7 May 2024 12:19:43 -0700 |
I'm in a state where `dabbrev--last-buffer' is set to #<killed buffer>,
which confuses the `dabbrev-completion' command as shown by the
backtrace below.
If I find a way to reproduce I will follow up with that.
I suspect that dabbrev.el should use `(buffer-live-p
dabbrev--last-buffer)' instead of checking for non-nil.
First, the value of dabbrev--last-buffer:
dabbrev--last-buffer is a variable defined in ‘dabbrev.el’.
Its value is #<killed buffer>
Not documented as a variable.
Second, what happens when I run `dabbrev-completion':
Debugger entered--Lisp error: (error "Selecting deleted buffer")
set-buffer(#<killed buffer>)
(progn (set-buffer dabbrev--last-buffer))

Thanks, I added the buffer-live-p tests where appropriate in
dabbrev.el and installed the changes on the master branch. I'm now
boldly closing this bug.
