Hello, I trust that this is the right place to report a segfault.
Using whatever is current in debian 9, emacs segfaults
from a minimum setup when using an empty string for org-ellipsis.
Here's how to reproduce it:
> emacs -Q
(setq org-ellipsis "") C-x C-e (org-mode) C-x C-e * asd ** def C-p
tab < and boom
My emacs isn't built from sources, so the ftrace/backtrace
is meaningless for the "Fatal error 11: Segmentation fault"
If there is a bugtracker and there always is a bugtracker,
then my apologies in case this has already been dealt with.

The right place to report emacs segfault (whether caused by another package
or not) would be by M-x report-emacs-bug from within emacs. If you haven't
set up to send emails from within emacs (I haven't), then copy the To email
address, email subject and the generated email body and email it it using
your default email client.

I can recreate that error on emacs master + org 9.0.9.

Once you send that bug report, you will get a debbugs number. Please post
that number in this thread (for people curious about this bug like me).

Meanwhile, we could simply change :safe keyword from `org-ellipsis' to
(lambda (v) (and (string-or-null-p v) (not (equal v ""))))
WDYT?

But that would still allow the user to use setq to set that variable.

True, but can we always prevent them from shooting themselves in the
foot?
Anyway, I updated the :safe value and changed the test below:
(vconcat (mapcar (lambda (c) (make-glyph-code c 'org-ellipsis))
(if (stringp org-ellipsis) org-ellipsis "...")))
