That looks closely related to the bug that was fixed by the
following patch:

http://review.gluster.org/#/c/10319/

In that case, the problem was with the allocation of members *within*
the log_buf.  In this case it's the allocation of the log_buf itself.
Looks like we just need to apply the same old_THIS trick in
log_buf_new.
