One problem that needs to be fixed is that fatal_error_signal/ 
shut_down_emacs/ns_term_shutdown essentially hides the bugs -- when  
Emacs runs into an abort(), this "cleans up" and makes sure there is  
no trace of the bug anywhere.  So we never find out what exactly hit  
Emacs.  I'd rather see a nice OSX crash report.

(Yes, I'm seeing random crashes, too, and an absolutely reproducible  
one that Adrian can't reproduce: Click on "Options" in the menu bar  
and Emacs is gone.  There must be something about my environment as  
well.)

"Options" doesn't cause a problem for me. Would it be useful to report  
back with some information about my setup to possibly eliminate  
sources of the problem?

I am using a copy of CVS of a few days ago.

Agreed.  With a crash report we'd have something useful to report,
otherwise we're just complaining.

I'm happy to put work into finding the bugs if I knew how.  The Intel
version I compiled from CVS doesn't have the problem you report with key
bindings and focus.

With two windows in one frame, coming from another Mac OS X  
application and you click into that window that does not have the  
cursor, this window gains the cursor?

Sorry, I misunderstood your example.  I can confirm it happens.

I've been using Gnus in the X11 Emacs build on Mac OS X for several
weeks now and have not experienced any epa-file GPG errors.  They only
happen with the Emacs.app Cocoa build from Emacs CVS.  You can reproduce
them easily:

1) install GPG in your path
2) load epa-file.el
3) C-x C-f /tmp/secret.gpg
4) C-x C-s (to save it); use symmetric encryption
5) kill the buffer
6) C-x C-f /tmp/secret.gpg; enter your passphrase again

Step (6) works fairly randomly, maybe 3-4 out of 10 times and usually
interleaving success with failure.  There's no obvious cause for the
error.

The X11 build has not crashed for me all this time, so I'm not eager to
use Emacs.app on Mac OS X and lose work randomly.  How can I help catch
these crashes so we can log and understand them?  Do we need other Cocoa
developers (which I am not)?

Thanks
Ted
