Not sure what is that you are trying to achieve, but with the
expression you wrote you are setting debug-ignored-errors to the return
value of beginning-of-buffer, which is nil when called like that. So
you end up not ignoring errors.
The doc string (which you can read by typing
`C-h v debug-ignored-errors RET') says it is a list, and with emacs -Q
its value is:
(beginning-of-line beginning-of-buffer end-of-line end-of-buffer
end-of-file buffer-read-only file-supersession mark-inactive user-error)
This setting is done in the file lisp/bindings.el, so you might want to
take a look at that file to see how it's done. Also notice
beginning-of-buffer is already an element of debug-ignored-errors.
If you really want to set debug-ignored-errors to only
beginning-of-buffer you can do the following:
(setq debug-ignored-errors '(beginning-of-buffer))
Best regards,
Mauro.
