I've recently been seeing this error more and more especially on GCC with -Wall:
/home/dean/boost/boost/optional/optional.hpp:407: warning: dereferencing pointer ‘<anonymous>’ does break strict-aliasing rules /home/dean/boost/boost/optional/optional.hpp:427: note: initialized from here

This is on Linux and GCC 4.4.1.
I'm not an expert in this regard but is there a way to either silence or avoid these warnings? Anything you want me to try from my end?
This was discussed in the past, and some people claimed the warning was spurious. I am personally not convinced whether it is spurious or not, however.
