Re: BUG ON librbd or libc

There was almost the exact same issue on the master branch right after
the switch to cmake because tcmalloc was incorrectly (and partially)
linked into librados/librbd. What occurred was that the std::list
within ceph::buffer::ptr was allocated via tcmalloc but was freed
within librados/librbd via the standard malloc.
