Thanks. Any chance of a recipe to reproduce this crash?
The backtrace indicates that the code which crashed was called from a
timer function -- any idea what timer was that?

I guess one of these fonts is faulty in some way? Or maybe you have
neither of these fonts on that system, which would effectively specify
that characters of the han script have no font at all? Of course,
normally the latter should just cause the han characters to display as
hex codes, not to cause crashes...
Are you saying that just having the above in your customization and
typing some Han character causes Emacs to crash?
P.S. And please use Reply All to reply, so that the bug address is
kept on the CC list.

when popup frame has the warning-icon (marked in picture) , emacs will
crash immediately.

Can you try the patch below and see if it prevents the crash in these
cases?

Actually, this is progress: we are now crashing a bit later, while
trying to display an empty box instead of a character that has no font
and no suitable face. To resolve this, please help me by providing
the results of the following GDB commands after Emacs crashes and GDB
kicks in:
(gdb) p it->face_id
(gdb) p it->c
(gdb) p FRAME_FONT(it->f)
(gdb) p (it->f)->output_data.x->font
Thanks.
