Hi all,

Since I upgraded glib from 2.32.1 to 2.34.1 on my system, I find
closing an emacsclient frame will first close all clients and then
make emacs hang. This happens to me with Emacs 24.2.1 and the latest
emacs-24 branch.

I can confirm that latest emacs-24 branch --with-x-toolkit=lucid works
fine, but since most gnu/linux users and distros compile emacs with
gtk, I think it's worth trying to fix whatever glib broke.

BTW I was trying to get a backtrace, but for some reason I can't
source the src/.gdbinit file, I get this all the time:

    .gdbinit:21: Error in sourced command file:
    No symbol table is loaded.  Use the "file" command.

gdb is version 7.5. Any help is appreciated.

Please tell how you invoke GDB, and what commands did you type inside
GDB since its invocation until "source .gdbinit".

You should do this:

  gdb -iex "set auto-load safe-path /usr:/bin:$(pwd)" ./emacs

IOW, you need to tell GDB from which executable to load the debug
info, including symbols.

Thanks, that helped.

Attached is the gdb session log, what I did is to start emacs as a
daemon, attach the process to gdb and then create two clients with
"emacsclient -c somefile". After closing the frame of one of these
created clients, emacs hangs. I have to kill it in order to get a
backtrace. Let me know if I could do something else to get better
information as I'm not knowledgeable at this.


BTW, what I'm using here is emacs compiled from emacs-24 branch, revno 110771.
