I feel obligated to point out the warning from /etc/defaults/make.conf:
# CFLAGS controls the compiler settings used when compiling C code.
# Note that optimization settings above -O (-O2, ...) are not recommended
# or supported for compiling the world or the kernel - please revert any
# nonstandard optimization settings to "-O" before submitting bug reports
# to the developers.
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.
