============
Warning!  Building Tor with --enable-fragile-hardening (also known as
--enable-expensive-hardening) makes some kinds of attacks harder, but makes
other kinds of attacks easier. A Tor instance build with this option will be
somewhat less vulnerable to remote code execution, arithmetic overflow, or
out-of-bounds read/writes... but at the cost of becoming more vulnerable to
denial of service attacks. For more information, see
https://trac.torproject.org/projects/tor/wiki/doc/TorFragileHardening
