[tor-relays] running Tor relay live with AddressSanitizer

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 probably create a static build, with 'libevent' and 'tor' compiled using

-fsanitize=address -O1 -fno-omit-frame-pointer -g

per the Google documentation and 'libz' compiled normally since 'zlib' is stable and mature.

Any thoughts or experience?

Thanks
