This strikes me as odd. The teeks99-02-dc3.0-11-Docker-64on64 is an *older*
version of clang, on the same version of ubuntu, but doesn't have this
issue. Is it possible this is an issue with boost's detecting of
compiler/stdlib capabilities that isn't working correctly here? If anyone
wants to play with this, the images on docker hub
teeks99/boost-cpp-docker:clang-3.0 and clang-3.1 (and clang-3.2 which is
again happy) can be used to figure out what is happening. All three use the
same ubuntu install (trusty), have identical Dockerfiles (except the clang
version), and use nearly identical lines in their user-config.jam files.
using clang : 3.1~c++11 : clang++-3.1 : <cxxflags>"-Wno-c99-extensions
-std=c++11" ;
