Anything that includes Boost.Exception is currently broken on master for 
all compilers, for example:

http://www.boost.org/development/tests/master/developer/output/teeks99-09j-win2012R2-64on64-boost-bin-v2-libs-exception-test-all_hpp_test-test-msvc-11-0-dbg-adrs-mdl-64-lnk-sttc-thrd-mlt.html

http://www.boost.org/development/tests/master/developer/output/Flast-FreeBSD10-gcc-5-3-0~gnu++11-boost-bin-v2-libs-exception-test-diagnostic_information_hpp_test-test-gcc-5-3-0-debug-link-static.html

The cause is the use of a partial-template specialization in info.hpp 
with no previous definition of class set_info_rv.

Thanks, John.
