I ran into, what I think is the same thing as you're describing, a while ago. The short and skinny being that -O0 doesn't compile any ASM which breaks things and is why you need at least -O to compile the kernel/world. ::shrug:: I could've botched that explanation, but it took me a while to track this down and have it explained. Kind of obscure IMHO. Someone suggested testing to make sure that at least -O is specified where needed, but I'm 99% sure I haven't seen that commit. -sc -- Sean Chittenden To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
