Comment (by rubiate):

 I've been able to reproduce this (on OpenBSD) a bit more easily than what
 attila described.

 Run tor normally and with a standard config, but with UseBridges enabled
 and the 2 relays attila posted as bridges. Start and stop tor and it will
 eventually produce this same crash on startup while updating the
 consensus.

 Running this gives the crash usually within about ~30 minutes:

 {{{
 #!/bin/sh
 while [ ! -e tor.core ] ; do
   tor --ignore-missing-torrc -f "" --bridge 66.111.2.16:9001 --bridge
 66.111.2.20:9001 --usebridges 1 &
   sleep 20
   kill -TERM $!
   sleep 3
 done
 }}}

 I couldn't reproduce this on Debian (with 0.2.8.7 compiled from source).
 Or on OpenBSD when I changed the bridge lines to use different relays
 (although I might be getting close to superstitious pigeon territory now).
