I'm seeing another uninitialized memory problem in bitcoind using valgrind:

I looked at this a bit more yesterday, and it looks like both sides of the
comparison were uninitialized, and I fixed one side, but the other side has
the same problem.
I'll try to investigate further this afternoon once I get out of
meetings/meetings prep.
