13399,pthread_create segfaults when program is restarted after some time,ttomas.mikalauskas@…,chris_kohlhoff,"Hi,

We are using boost 1.56 version on CentOS 7.4.1708 (Core)

This bug happens from time to time when we are restating application, while simulated multiple clients send message to the server.
