libpmemcto1 1.4.1-0ubuntu1~18.04.1 (amd64 binary) in ubuntu bionic

 The libpmemcto library is a persistent memory allocator providing malloc-like
 interfaces, with no overhead imposed by run-time flushing or transactional
 updates. An overhead is imposed only when program exits normally and have to
 flush the pool contents.

 NOTE: This is an experimental API and should not be used in production
 environments.
