Ummm, I need information about the combination of font and
character that crashes Emacs.

When you get a crash as this:

Program received signal SIGSEGV, Segmentation fault.

Please try these commands:

(gdb) up 2
(gdb) p font
(gdb) pr	<- this prints the font name
(gdb) up 2
(gdb) p/x c	<- this prints the character code in hex.
