Fwd: [Aquamacs-bugs] C++ program auto-insertion fails with Aquamacs 1.3

Fwd: [Aquamacs-bugs] C++ program auto-insertion fails with Aquamacs 1.3

[David Reitter]

Is this a known bug with the 22 branch?
(Don't know enough about C++ mode to attempt to reproduce this.)

Ask him to give a recipe,

Assuming you mean steps to reproduce, here's an attempt at that. I  
haven't tried to do this in isolation with an empty .emacs yet. Sorry.

*** To reproduce:

Evaluate (from my .emacs):
(add-hook 'find-file-hooks 'auto-insert)

Enter:
C-x C-f ~/foo.hpp RET
y (when prompted to "Perform C / C++ header auto-insertion")

*** Expected behaviour:

The newly created buffer, visible, with the following contents:
===
#ifndef FOO_HPP
#define FOO_HPP

<cursor here>

#endif
===

*** Actual behaviour:

Same buffer that was visible before is visible. When switching to the  
newly created buffer, it contains:
===
#ifndef <cursor here>
===

And the *Messages* buffer contains:
===
(New file)
Perform C / C++ header auto-insertion? (y or n)
byte-code: End of buffer
===

We need the staeps to start from a clean slate.  I.e. "emacs -Q".

OK. I've verified that those same steps I described, starting aquamacs  
with -Q, cause the same problem.

Can't reproduce it here with Emacs-22.1.92.
Please set Options => Enter Debugger on Error
and then reproduce the problem.  You'll then hopefully get a backtrace
which will be informative.

No such luck; no debugger pops up.

Try additionally to enabling the debugger, to also do

  M-: (setq debug-ignored-errors nil) RET

and re-trigger the bug.  Hopefully you'll get a backtrace this time.

Okay, I managed to reproduce this with Aquamacs 1.3a (compiled from 22  
branch CVS, 2008-02-23), but not with the current nightly build.

The stack trace is below. I suspect the following check-in fixed the  
bug.

Thanks David, I've confirmed that this bug doesn't appear with the  
latest nightly build.
