Emacs hangs when point enters a word that is highlighted by flyspell.
I cannot reproduce this on an NS build, so I originally thought it was
limited to the mac-port. However the maintainer reproduced it with the
emacs-26 branch, both on GTK+ and Athena toolkits.
Recipe:
Emacs -Q
(setq mouse-highlight 1)
(flyspell-mode 1)
"Misspetl wd " ;enter some text that becomes marked by flyspell
;place the mouse pointer over the word "Misspetl"
;hold the left cursor key until point moves back to the word "Misspetl"
Emacs hangs with repeating error "Marker does not point anywhere". You
can clear the hang by moving the mouse pointer.

Not reproducible here. Could this be X-specific (I tried on Windows)?

I can reproduce this in emacs-26 (Ubuntu 17.10 with GTK3 here).

I can see it as well on emacs 27, Ubuntu 17.10 w/ GTK3. This is where it
comes from:
Thread 1 "emacs" hit Breakpoint 1, marker_position (marker=0x3463451) at
marker.c:641
641 error ("Marker does not point anywhere");
(gdb) l
636 {
637 register struct Lisp_Marker *m = XMARKER (marker);
638 register struct buffer *buf = m->buffer;
639
640 if (!buf)
641 error ("Marker does not point anywhere");
642
buf is null.
It's a bit too late here to dig into this more.

Thanks.
A C- and Lisp-level backtrace from the place which signals that error
would be helpful.

Can you please try the attached patch. I have no idea whether this is
the correct interpretation of the semantics of 'mouse-highlight'.
