Please try your setup with the a "normal" CFLAGS (ie -O -pipe) and then see if you get a reproducible panic. If you do, then report it to the mailing list. Otherwise, you are a victim of a *known* bad code optimizer which you were warned about. -gordon To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
