This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org. Please check that
the From: line contains a valid email address. After a delay of up
to one day, you should receive an acknowledgment at that address.
Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.
Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug. If you can, give a recipe
starting from `emacs -Q':
I cannot give a recipe for this crash as it happens after running
approximately for a week. I ran emacs compiled with debugging symbols
and in gdb to get a backtrace which I will include below:

The emacs binary has been built with the debugging flag added "-g". I
don't know the code base and the image cache logic well enough, but it
seems that cache_image lacks a check for the FRAME_IMAGE_CACHE macro
returning 0x0.
I will happily retry to reproduce this with further debugging info
added should that be of help.
If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
`bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file

Thanks. I've committed a fix for this problem in the upcoming Emacs
25.1.
