You're completely sure that's the 1.4.20 source tree? That bug was pretty well fixed...
If you are definitely testing a 1.4.20 binary, here's the way to grab a trace: start memcached-debug under gdb: gdb ./memcached-debug > handle SIGPIPE nostop noprint pass > r T_MEMD_USE_DAEMON="127.0.0.1:11211" prove -v t/lru-crawler.t ... wait until it's been spinning cpu for a few seconds. Then ^C the GDB window and run "thread apply all bt" .. and send me that info.
