Hello. Thanks for replying.

No. There is no crash, just illegal instruction. And it happens after
the function run over.

After recheck the document,
https://www.boost.org/doc/libs/1_63_0/doc/html/boost_asio/using.html

BOOST_ASIO_DISABLE_THREADS

Explicitly disables Boost.Asio's threading support, independent of
whether or not Boost as a whole supports threads.

I find by -DBOOST_ASIO_DISABLE_THREADS the code works fine.

Still don't know why
