Emacs open big Org-mode file error

Emacs open big Org-mode file error

[stardiviner]

I have a big Org-mode file about 1.3M.

When I open it, Emacs crash. Then I try to do a simple GDB debug:

```

gdb /usr/local/bin/emacs

```

Got output:

```

Please report all this to the Emacs issue tracker using the command
"M-x report-emacs-bug RET".  Please attach the Org file if that's
possible.

Thanks.
