Compilation with Werror broken for clang

[PSIAlt]

Im using BOOST_VERSION 105800

Took echo server example from here http://www.boost.org/doc/libs/1_54_0/doc/html/boost_asio/example/cpp03/spawn/echo_server.cpp

And compiling with clang (Apple LLVM version 8.0.0 (clang-800.0.38)): g++ echo_example.cpp -o echo_example -I/usr/local/include -std=c++11 -Wall -Werror -ggdb3 -O2 -Wno-unused-local-typedef -isysroot /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.12.sdk -Wno-deprecated-declarations

It gives warnings below and -Werror makes it not compile. With option -Wno-delete-non-virtual-dtor it does build normally. This may or may not be a bug

I'm having the same issue, with clang version "Apple LLVM version 8.0.0 (clang-800.0.42.1)". Its probably an error with boost_coroutine and we should report it there.

I am having this issue as well: http://www.boost.org/development/tests/develop/output/teeks99-02-dc3-9-14-Docker-64on64-beast-clang-linux-3-9~c++14-warnings.html#buffered_read_stream
