WARNING: This bug is difficult for me to reproduce. I hope I found a minimal example which exhibits the bug for everyone, but things like display resolution or X settings may have an influence, so you may have a hard time reproducing it. That said ... I see Emacs segfaulting when moving the cursor upwards in a LaTeX document while tex-fold-mode is active. The starting position of the cursor is important. I placed all files to reproduce the bug at <http://wilson.bronger.org/emacs-glyph_row-bug.tar>. The TeX file needs to be put in /tmp. tex-fold-mode must be present. Furthermore, place .emacs and .emacs.desktop in the proper positions, start current Git Emacs, and press the "cursor up" button. Then, Emacs crashes for me. The subject of this bug is just to give it a name. I do not know whether glyph_row is the issue. However, I bisected the problem, and it started with commit f425a774, which sets glyph_row to NULL in two places. If I revert this commit, the problem is gone.

Ouch! what a terrible blunder! Sorry about that; I see the problem
and am working on a solution.

OK, so I tried this: 0. mkdir /tmp/emacs-bug 1. mv test.tex .emacs .emacs.desktop /tmp/emacs-bug 2. cd /tmp/emacs-bug 3. HOME=`pwd` emacs 4. M-x package-install RET 5. [Install auctex] 6.

Should be fixed now, please try the latest master branch. If there
are any adverse effects of the change I installed, please tell the
details.

Thanks, I'm therefore closing this bug report.
[-- Attachment #1: Type: text/plain, Size: 642 bytes --] I've run into this bug after upgrading from Emacs 27.1 to 27.2, rebuilt Emacs with debug symbols and managed to chase it down to a line in xdisp.c dereferencing a null pointer today. Running `git blame` pointed me towards this thread. While the bug has been fixed on master and it's rather tricky to reproduce (it involves at least one third party package for me and typing a long line at the end of the window that then wraps around), I'd be inclined to call 27.2 more than just a bugfix release due to the xdisp.c change introducing this bug. Is there a chance that a patch can be published for the 27.2 release for downstream maintainers? [-- Attachment #2: signature.asc --] [-- Type: application/pgp-signature, Size: 488 bytes --]

I don't understand what that means in practice. Can you elaborate,
please?
[-- Attachment #1: Type: text/plain, Size: 595 bytes --] > I don't understand what that means in practice. Can you elaborate, > please? The Emacs package on Arch Linux [1] applies three patches to avoid fontconfig-related crashes when loading up color fonts [2]. The changes for this bug look more complicated and might need adjustments to apply cleanly to the 27.2 release. If that's indeed the case, then I'd try to get the Arch Linux maintainer to apply it to their Emacs package to avoid that particular crash.

Let me know if it doesn't apply cleanly.

These three patches are already included in the Emacs 27.2 (and in the
Emacs 26.3) release AFAICS.

It seems they aren't applied during the build process, so it looks like the package maintainer forgot removing them.
