[-- Attachment #1 --] Hi, > Hi today, cvsup'ed my source and build world ... > and now get an so called > > Bus error > > while i want to su, anyone know about it (or fixed it) I think the best is to build debugging version of su: # cd /usr/src/usr.bin/su # make clean # make depend # set CFLAGS="$CFLAGS -g" # make # install -o root -g wheel -m 4555 -fschg /usr/obj/usr/src/usr.bin/su/su /usr/bin ( 'make install' will strip the binary and all the nice debug info is gone) Now run su in the debugger, and will probably get a core dump: gdb /usr/bin/su GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.
