Hi!

I am trying to make a custom function for org-roam which inserts
footnote-like links in the current note. I'm using doom-emacs.

The idea is to insert links in this way

    The logistic regression [fn:20200612000001]...

    * Footnotes

    [fn:20200612000001] [[file:
20200612000001-definition_logistic_regression.org][Logistic regression]]

and the linked file has the form

    :PROPERTIES:
    :ID: 20200612000001
    :END:
    #+TITLE: Definition Logistic Regression

I just copy-pasted the original `org-roam-insert` function and hacked it a
little to insert the footnote. The code is here
https://gist.github.com/maikol-solis/ed149c16cff16a55492d1acba8c12025.

Everything is fine except that after a couple of times using it, emacs
crashes completely.  I think that is caused by this function because this
has never happened before.

I used `gdb` to follow the crash and this is the output:

     Thread 1 "emacs-gtk" received signal SIGSEGV, Segmentation fault.
     gui_produce_glyphs (it=0x7fff82fc3650) at xdisp.c:29925

     The program no longer exists.

I appreciate any help to solve this issue.
Best.

Is this a normal build of Emacs, or did you build some branch of the
Git repository?  (I'm puzzled why the thread is called "emacs-gtk".)

At this point, please say

   (gdb) source /path/to/emacs/src/.gdbinit
   (gdb) bt

(replacing "/path/to/emacs" with the real location of the Emacs
sources on your system) and post the result.

Hi Eli,

My emacs is the compiled in the editor's repo for 15.2 (
https://build.opensuse.org/package/show/editors/emacs), so I haven't any
control on how it was compiled.

With respect to the bug, I could reproduce it when I tried to replace a
link in org-roam. Here it is the full backtrace.

Thanks.  This is a duplicate of bug#44111, which is already fixed for
the upcoming Emacs 27.2.  If you can find a binary of the pretest
Emacs 27.1.90, you should see this problem gone there.

Thanks Eli. I will install this version until 27.2 lands into the oficial
repo.

Your help is much appreciated.

Best.
