CFLAGS=-O2 -pipe problems in RELENG_5 ?

[Mike Tancsa]

I did a buildworld /buildkernel with a RELENG_5 box using the following flags


CPUTYPE=i686
KERNCONF=recycle
CFLAGS=-O2 -pipe
COPTFLAGS=-O2 -pipe
NO_MODULES=true    # do not build modules with the kernel
MODULES_WITH_WORLD=true # do not build modules when building kernel

After rebooting and trying to repeat the process, I get the following

[ns4-new]# rm -R /usr/obj/
[ns4-new]# make buildworld

If I change it back to just -O, it builds just fine.  I thought RELENG_5 
was supposed to be safe with -O2 ?
