Description

Hi,

I built Boost 1.53.0 on Fedora 18 32/64-bit using the following command:

./b2 link=shared runtime-link=shared address-model=32|64 variant=release

and received the following messages during the compilation:

libs/python/src/object/enum.cpp: In function ‘boost::python::api::object boost::python::objects::{anonymous}::new_enum_type(const char*, const char*)’: libs/python/src/object/enum.cpp:150:44: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/class.cpp: In function ‘PyObject* boost::python::objects::static_data()’: libs/python/src/object/class.cpp:211:46: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/class.cpp: In function ‘boost::python::type_handle boost::python::objects::class_metatype()’: libs/python/src/object/class.cpp:319:49: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/class.cpp: In function ‘boost::python::type_handle boost::python::objects::class_type()’: libs/python/src/object/class.cpp:473:45: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/function.cpp: In constructor ‘boost::python::objects::function::function(const boost::python::objects::py_function&, const boost::python::detail::keyword*, unsigned int)’: libs/python/src/object/function.cpp:108:39: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/function.cpp:110:39: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/life_support.cpp: In function ‘PyObject* boost::python::objects::make_nurse_and_patient(PyObject*, PyObject*)’: libs/python/src/object/life_support.cpp:94:43: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing] libs/python/src/object/life_support.cpp:96:43: warning: dereferencing type-punned pointer will break strict-aliasing rules [-Wstrict-aliasing]

These warnings are still appearing in Boost 1.54.0
