  Description     : hardened memory allocator
This is a security-focused general purpose memory allocator providing
the malloc API along with various extensions. It provides substantial
hardening against heap corruption vulnerabilities. The security-focused
design also leads to much less metadata overhead and memory waste from
fragmentation than a more traditional allocator design. It aims to
provide decent overall performance with a focus on long-term performance
and memory usage rather than allocator micro-benchmarks. It offers
scalability via a configurable number of entirely independently arenas,
with the internal locking within arenas further divided up per size
class. It can be added as a preloaded library using /etc/ld.so.preload.
