Re: [O] Emacs sagmentation fault error on a big org-mode file movement

[Neil Jerram]

I would suggest (but without detailed knowledge of current emacs practice):

1. Report your exact emacs version.

2. Install a corresponding debug symbols package, if your distro provides that.  That should add a lot more interesting detail to the backtrace.

3. To go further, repro under GDB, ideally with corresponding source code.  Then you could explore the immediate cause of the segfault.

Here is the output from command-line:

Is there a way to debug this?

I know it is not possible to invoke edebug on anything internal Emacs.

So is there any system (Linux)  solution?

Like system process dump or traceback.

I'm using latest version `master` branch source code Org-mode.

Emacs is from compiled `master` branch  source code too.
