+Report crashs
+~~~~~~~~~~~~~
+
+If you experienced crashs, or if you want to report any future WeeChat crash,
+you have to:
+
+* compile it with debug info (or install binary package with debug info)
+* enable 'core' files on your system
+* install gdb
+
+[[debug_info]]
+Debug info
+^^^^^^^^^^
+
+If you're compiling with cmake:
+
+----------------------------------------
+$ cmake .. -DCMAKE_BUILD_TYPE=Debug
+----------------------------------------
+
+If you're compiling with autotools, debug is default (`--with-debug=1`).
+
+If you installed a binary package, then install package 'weechat-dbg'.
+
+[[core_files]]
+Core files
+^^^^^^^^^^
+
+To enable 'core' files, you have to use `ulimit` command.
+
+For example under Linux with 'bash' shell, add this line to your `~/.bashrc`:
+
+----------------------------------------
+ulimit -c unlimited
+----------------------------------------
+
+Or max size:
+
+----------------------------------------
+ulimit -c 200000
+----------------------------------------
+
+[[gdb_backtrace]]
+Get backtrace with gdb
+^^^^^^^^^^^^^^^^^^^^^^
+
+When WeeChat crashes, your system will create a file 'core' or 'core.12345'
+('12345' is process id).
+This file is created in directory where you have run WeeChat (this is *not*
+directory where WeeChat is installed!).
+
+For example if 'weechat-curses' is installed in '/usr/bin/' and 'core' file is
+in '/home/xxx/', then run gdb with this command:
+
+----------------------------------------
+gdb /usr/bin/weechat-curses /home/xxx/core
+----------------------------------------
+
+Then under gdb, use command `bt` to display backtrace.
+You will see something like that:
+
