If you followed the links to
https://stackoverflow.com/questions/35225234/linking-libboost-log-so-makes-boostasioio-servicerun-exit-immediately/35241050#35241050,
there is

"Boost.Log does indeed use Boost.ASIO to implement some of its features
(network-based syslog sink, in particular). Boost.ASIO marks its symbols as
externally visible, so they are exported from Boost.Log shared object."

Note that the crashing code does not use network based syslog. Boost.log
may not intend to always have a dependency on boost.asio, but it appears it
does.
