Hello, I'm asking for permission to merge the following commit chain into release: https://github.com/boostorg/poly_collection/commit/3609895bd01e5add5971345a3... https://github.com/boostorg/poly_collection/commit/18b7d88df360001c2c006f021... https://github.com/boostorg/poly_collection/commit/ce7e7aac60747c6fad5e97d2c... https://github.com/boostorg/poly_collection/commit/ab32df47f8811dc7f136a166f... https://github.com/boostorg/poly_collection/commit/df754527917b7be013ce558f8... Fixes bring compatibility with Clang 3.3 and solve a potential UB problem related to CWG 232 and detected at http://www.boost.org/development/tests/develop/developer/Marshall-UBSAN-poly... I'm waiting for Marshall-UBSAN to cycle through these but all recently updated test runners are working fine. Clang 3.3 is already verified to work by teeks99-02-dc3.3-11-Docker-64on64. Thank you, Joaquín M López Muñoz
