      qpid::linearstore::journal::pmgr::initialize(qpid::linearstore::journal::aio_callback*, uint32_t, uint16_t)':
      /foo/cpp/src/qpid/linearstore/journal/pmgr.cpp:115:68: error: 'void* memset(void*, int, size_t)' clearing an object of non-trivial type 'struct qpid::linearstore::journal::pmgr::page_cb'; use assignment instead [-Werror=class-memaccess]
           std::memset(_page_cb_arr, 0, _cache_num_pages * sizeof(page_cb));
                                                                          ^
