Oh, I use GCC 2.7.2.3 ... So I rebuilt XEmacs with -fno-caller-saves, but it seems not changes. XEmacs still crashes. When I make optimize level down to -O2 and then -O, it seems same. I append "Installation" and GDB out put. I'll check them. _/ Kazuo Oishi Yamaguchi Univ. _/_/ _/_/ oishi(a)ae.agr.yamaguchi-u.ac.jp _/ uname -a: Linux agenv4 2.0.34 #1 Sat Jul 4 11:01:03 JST 1998 i586 unknown ./configure '--cflags=-g -O3 -Wall -Wno-switch -fno-caller-saves' '--with-mule' '--with-xim=no' XEmacs 21.0 "Benadir" configured for `i586-pc-linux'.
