Does it affect boost::variant too?
Yes, it does for me: /home/mlcreech/svn/PCM-tk/trunk/vendor_export/include/boost/variant/detail/backup_holder.hpp: In member function 'virtual int CTrendThread::wait_for_events()': /home/mlcreech/svn/PCM-tk/trunk/vendor_export/include/boost/variant/detail/backup_holder.hpp:67: warning: dereferencing pointer '<anonymous>' does break strict-aliasing rules /home/mlcreech/svn/PCM-tk/trunk/vendor_export/include/boost/variant/detail/cast_storage.hpp:33: note: initialized from here this is triggered by a call to boost::apply_visitor.
