Architecture: alpha
Machine: alpha
>Description:
	programs linked with crt*.o compiled with gcc -O3 after the
	recent .init/.fini changes in lib/csu die with "illegal
	instruction" or "bus error"

>How-To-Repeat:
	add "COPTS+=-O3" to /etc/mk.conf
	# cd /usr/src/lib/csu
	# make clean all install
	# cd /usr/src/bin/ls
	# make clean all
	# ./obj/ls

>Fix:
	don't use "gcc -O3".  i've been told higher optimisations
	aren't supported; if that's the case we should modify the
	gcc front end to limit the level on a given platform to
	what that platform can reliabily generate code for (or does
	that imply -O0 ? :-)
