Finally got around to compiling 'openssl'
and 'libevent' with AddressSanitizer.
Found and patched one minor bug as
a consequence
https://trac.torproject.org/projects/tor/ticket/12227
After running for a week the relay lost
its guard status due to declining
BWAUTH measurements. At the time

I updated the patch to
1) have AS close /proc
2) enable core dump files
One should add
/proc /chroot_tor/proc none noauto,bind 0 0
to /etc/fstab (note the 'noauto').
Then the 'tor' startup script does a
mount /chroot_tor/proc
...start tor
sleep 10
umount /chroot_tor/proc

Based on my experience today, I'd say this is
an excellent idea for any Tor relay operator.
Have been running 'tor' on the router since
late November with AddressSanitizer and
it has crashed exactly ONE time: Today
when someone attempted to apply the
OpenSSL "Heartbleed" attack against
the relay.

Took an initial jab at it by compiling
just 'tor' with
CFLAGS = -g -O1 -D_FORTIFY_SOURCE=2 -fstack-protector-all -Wstack-protector
Has anyone tried running a live relay with
an image built using GCC 4.8 and
-fsanitize=address?
AddressSanitizer documentation says it should
be no worse than about x4 on CPU and typically
about x2, so it looks reasonable to try.
I'm seeing peak CPU of about 7-8% of a 2.2GHz
AMD core.
I'd probabl
