Message #5 received at submit <at> debbugs.gnu.org (full text, mbox):
Package: cc-mode
Start with the following code in a c-mode buffer:
static struct test_subsurface *
make_test_subsurface (void)
{
struct test_subsurface *subsurface;
subsurface = malloc (sizeof *subsurface);
if (!subsurface)
goto error_1;
subsurface->surface
= wl_compositor_create_surface (display->compositor);
if (!subsurface->surface)
goto error_2;
subsurface->subsurface
= wl_subcompositor_get_subsurface (subcompositor,
wayland_surface,
display->surface);
error_2:
free (subsurface);
error_1:
return NULL;
}
move point to the end of the line before "error_2". Type:
s u b s u r f a c e - >
then, hesitate for 1 second, and type:
<backspace> <backspace>
wait 1 more second, then type:
<up>
every occurrence of "subsurface" above will become fontified as a type,
and will be stuck that way until you make an edit above that occurrence.

I have a fix for this, I think, but it overlaps with an earlier fix to
bug #58883. I sent you a patch on Sunday 2022-10-30 for this earlier
bug. Did you get this patch? If so, have you any reaction to it?
It would help me keep things straight if we could commit that patch to
#58883, and then create another patch for the current bug.
Thanks!

I think it got lost in the bulk mail folder (but I can't find it there
either, so maybe a mailer screwup?)
So would you please send it again? TIA.
