eval-region & switch-to-buffer error

[Shawn Betts]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

in *scratch* type the following (make sure your "foo" buffer doesn't exist):

(message "here")
(switch-to-buffer "foo")
(message "there")

set the mark at the beginning of the first line then move the point to
the line after the last line.

M-: (eval-region (mark) (point)) RET

I get the error:

Debugger entered--Lisp error: (args-out-of-range 1 472)
  eval-region(412 472)  ; Reading at buffer position 472
  eval((eval-region (mark) (point)))
  eval-expression((eval-region (mark) (point)) nil)
  call-interactively(eval-expression)

I imagine its because the current buffer is no longer *scratch* and so
point 472 is invalid in the empty buffer "foo".

If emacs crashed, and you have the emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
If you would like to further debug the crash, please read the file
/home/sabetts/opt/share/emacs/22.0.50/etc/DEBUG for instructions.
