The stacktrace is nice, but the lruhash code did not change between
1.3.4 and 1.4.1.

Artis noted that it seems to be running fine with "validator iterator"
module-config statement (not without the validator).  Could this be the
same for you?

Other than that I have no clues except it seems to fail for both of you
FreeBSD.  But my tests on FreeBSD8 all work well.
libevent/libev/builtin does not make a difference.  Could check
with/without-pthreads.  Could try without a cache (0 sizes, the malloc
behaviour should be very simple).  valgrind is typically very good at
spotting such heap-corruption or double free-s (if it works well enough
for you).

But if those stackdumps are the same that would be interesting...
