Subject: 25.2; emacs crashes after lisp started
--text follows this line--

1) start emacs.
2) ctrl-x l to start lisp in a *common-lisp* buffer (I use ACL 10.1)
3) click on any menu (e.g., edit, options, tools)
4) emacs will crash with the single line of output on the cmd line:
"objc[17271]: Invalid or prematurely-freed autorelease pool 0x104002140."

Hi Pete, thanks for reporting this.

Is there any chance you could try the master branch or a nightly
build? There have been a few crash fixes made in it.

Hmmmm, stranger and stranger. I would expect the binary to be
essentially identical to the homebrew version.

I believe you can build the master branch in homebrew using:

    brew install emacs --HEAD --with-cocoa

I'll give it a shot and get back to you.

bug#26982: 25.2; emacs crashes after lisp started

Alan,

Okay, I made emacs from HEAD, but the same problem occurs, and there are 
other things that are flakey (the Lisp version doesn't show and the 
menus don't have all the options (before I start lisp)), so I went back 
to the stable version.

But here's an interesting observation: on my macbook-pro I can do fn-10 
and the menus show up as a drop down in my emacs window -- and they all 
work!

So I guess that means the problem is related to the interface with the 
mac, maybe with xcode?

It could be worth updating to the latest versions of everything. I
don’t know.

Are you able to run Emacs in a debugger and get a backtrace when it
crashes?

I'm swamped right now, but will look for some time. Could you point me 
to the steps on how to do that?

On macOS the easiest way is probably to use lldb. You’d do something
like

    $ lldb /path/to/Emacs
    > run

and once it crashes:

    > bt all

for the backtrace.

It would be best if you could build with debug info. The instructions
for that are in etc/DEBUG.
