This bug report will be sent to the Bug-GNU-Emacs mailing list and the GNU bug tracker at debbugs.gnu.org. Please check that the From: line contains a valid email address. After a delay of up to one day, you should receive an acknowledgement at that address. Please write in English if possible, as the Emacs maintainers usually do not have translators for other languages. Please describe exactly what actions triggered the bug, and the precise symptoms of the bug. If you can, give a recipe starting from `emacs -Q': Please read the main issue on step 8 first. This stuff is just a crazy workaround for that. 1. Started emacs on mac os x lion 10.7.3 2. Started shell M-x shell 3. Created buffer with very long text name starting with 4 spaces c-x b c-q spc c-q spc c-q spc c-q spc Now, start the server and you are ready to sign in and sign out. You can also block user access in any controller by calling authenticate_user! in a before filter. Just remember that, if you add the filter to your application controller, remember to skip the filter on the sessions controller, otherwise you won’t be able to sign in in the first place. 4. confirm with a 'return' 5. Repeat with slightly more spaces and complex buffer name c-x b c-q spc c-q spc c-q spc c-q spc c-q spc c-q spc You can now freely proceed to implement the other controllers and views in your application. Keep in mind that if you have devise :recoverable in your model, all the related methods like User.send_reset_password_instructions will already be available in your model, so you can use them straight away to implement your own reset password feature. Since Devise use all those methods internally, if you have any questions about implementing your own reset password feature, you can always take a look at Devise own controllers for some help. confirm by 'return' 6. Emacs hangs using ~100% of cpu 7. I sampled emacs from the activity monitor and attached file. 8. Reason: Why would anyone want to do this you ask. Please see: https://gist.github.com/2127333 It turns out emacs will read the name of the buffer when requested to read the highlighted text. So the above is a workaround for the real problem. 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'.
