The call-stack from the dump file shows my app(TMSClient100) called websocketpp::endpoint, then it called boost::random::random_device

If #1, this might be solved by upgrading from Boost 1.55 to a newer version. This fix in particular: https://github.com/boostorg/random/commit/dc2fdeac443fb56c87a03a0887c9 e7c8 e1d3296d went into Boost 1.56.
