That free_frame_faces has been the sole caller of this function for
quite some time, and it already performs the same test around its call
to free_image_cache.

Thanks, but I don't think I understand this part of the change you
installed:
--- a/src/image.c
+++ b/src/image.c
@@ -2304,23 +2304,18 @@ uncache_image (struct frame *f, Lisp_Object spec)

}
This basically removes the test of 'c' being non-NULL, leaving the
rest of the code unchanged. But if 'c' is NULL, dereferencing it in
the following code will segfault, so why remove the test? In
particular, what about frames that were not yet allocated the image
cache (could this happen with TTY frames, for example)?
What am I missing here?

OK, I believe I understand the source of these crashes. A frame whose image cache is shared among several frames is destroyed, but its `image_cache' field is never cleared after it is destroyed, as its cache continues to be referenced, and, if references to the dead frame remain, GC attempts to mark the said image cache although its validity is no longer guaranteed. In earlier Emacs versions, this problem would have appeared if references to dead frames were preserved beyond the destruction of a display structure. This has been corrected on the emacs-30 branch, and therefore if the crashes do not resurface in a few days, I will close this ticket. Thanks.

Can you establish when > the frame in question was created, how and where it received its current > image cache, and whether this frame exists in Vframe_list? I'm afraid I'm not familiar with any of these data structures. I don't know what these image caches are. In the mark_frame stack frame I did "p f" to obtain the address 0x555559f61330. I then did the "while $cons" thing you posted in another message, and searched its output for this address, and it is not present. So perhaps this means the frame is not present in Vframe_list. -- Sean Whitton

Can you establish when the frame in question was created, how and where it received its current image cache, and whether this frame exists in Vframe_list? If the answer to the final question is no, can anyone surmise how it is that a live frame's image cache might be prematurely deleted without its references being detected by verify_image_cache_refcount?

Can you suggest a GDB setup for Sean to use in order to try to find this unknown code which causes this? Please note that this affects the release branch, and the changeset which seems to have caused it was installed a couple of days before the release branch was cut. So if we cannot find and solve the problem soon enough, I'd revert that changeset and solve the original problem which it was supposed to solve on master, rather than leave such a serious problem on the release branch.

How does this answer my question?
The use case I was thinking of is that the image cache was shared,
then the last frame which shared the cache was deleted. How do we
make sure the cache is freed and set to NULL in this situation?
IOW, we seem to have a cache that is not NULL but is also not a real
cache, as it cannot be accessed. The question is how did that happen?

There's only one caller of free_image_cache, free_frame_faces, which is
only called once in a frame's existence. Cache refcounts are also
altered from gui_set_font, but this process never entails decrementing a
refcount to zero, as the caches under consideration are always retained
by one or more frames:
iwidth = max (10, FRAME_COLUMN_WIDTH (f));
if (FRAME_IMAGE_CACHE (f)
&& (iwidth != FRAME_IMAGE_CACHE (f)->scaling_col_width))
{
eassert (FRAME_IMAGE_CACHE (f)->refcount >= 1);
if (FRAME_IMAGE_CACHE (f)->refcount == 1)
{
/* This frame is the only user of this image cache. */
FRAME_IMAGE_CACHE (f)->scaling_col_width = iwidth;
/* Clean F's image cache of images whose values are derived
from the font width. */
clear_image_cache (f, Qauto);
}
else
{
/* Release the current image cache, and reuse or allocate a
new image cache with IWIDTH. */
FRAME_IMAGE_CACHE (f)->refcount--;
FRAME_IMAGE_CACHE (f) = share_image_cache (f);
FRAME_IMAGE_CACHE (f)->refcount++;
}
}

The packages I have installed don't do that, but I have tonnes of custom
code in my init.el to create new frames and adjust font sizes.
I normally have >=three frames open for each of two instances of Emacs.
I have two entries in window-size-change-functions:
--8<---------------cut here---------------start------------->8---
(defun spw/maybe-scale-basic-faces (frame)
"Entry for `window-size-change-functions' to increase font sizes,
relative to those set by the call to `custom-theme-set-faces' above, for
frames on wide monitors, except where doing so would itself prevent fitting
two 80-column windows side-by-side in the frame."
(when (display-graphic-p frame)
