Boost ticket #6766 ( https://svn.boost.org/trac/boost/ticket/6766 ) affects several of our tests running with Oracle Solaris Studio compiler. It prevents building of libboost_unit_test_framework.a which in turn causes tests from many of the libraries (accumulators, algorithm, assign, lexical_cast, msm, odeint, polygon, range and sync) to fail due to a dependency on libboost_unit_test_framework.a. A PR for this has been submitted.https://github.com/boostorg/test/pull/36 This fix alone causes the pass rate for Boost 1.58 with the Oracle Solaris Studio compiler to increase by about 15%. This fix is not in the 'develop' branch yet. We would very much appreciate if this could be considered for putback into the Boost 1.58 release. Thanks, Aparna
