c++ - Server with libpion crashing at request handling -
i use following versions of libraries: libpion-dev 5.0.6 libboost-all-dev 1.58.0 in internet found simple example of asynchronous http-server, falls in processing of requests handler described. in addition, non-existent resources correctly returns 404 response.

i'm not expert in pion library. however, reason why request /none returns 404 without crashing because it's being handled pion library not handle_request function.
there example of using pion library here. may discover what's going wrong in handle_request function.
