Exception thrown when using syslog_backend and a separate asio_server with a udp socket

[Philip Joseph <philip.joseph@…>]

When I try to setup a syslog_backend in a code base that already has an asio_server that opens UDP sockets, an exception gets thrown.

I am building with gcc 4.8 on ubuntu 14.04.

I compile my program as such:

/usr/bin/c++ -Wall -Werror  -std=c++11 -g -I/home/Phil/work/3p/posix-x86_64/boost@1.60.0/include -MMD -MT boostTestProject/CMakeFiles/BoostExe.dir/main.cpp.o -MF "boostTestProject/CMakeFiles/BoostExe.dir/main.cpp.o.d" -o boostTestProject/CMakeFiles/BoostExe.dir/main.cpp.o -c /home/Phil/work/Testing/boostTestProject/main.cpp

usr/bin/c++   -Wall -Werror   -std=c++11 -g   boostTestProject/CMakeFiles/BoostExe.dir/main.cpp.o -o boostTestProject/BoostExe  -rdynamic /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_log.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_log_setup.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_system.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_filesystem.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_date_time.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_program_options.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_thread.a /home/Phil/work/3p/posix-x86_64/boost@1.60.0/lib/static/debug/libboost_chrono.a -lpthread -lrt

Below is a capture of the stack trace and error I get:

Actually, I figured out our issue. We needed to add c++11 compile flags to our static builds of Log.
