Hi Richard, If you want to make a patch that silences the warning, that would seem reasonable to me. Thanks, Eric On Tue, Apr 22, 2008 at 2:38 AM, Richard Webb <richard.webb@boldonjames.com> wrote:

As we tried to update to 1.35 today, we found some warnings with MSVC on Warning Level 4 in:
lexical_cast: There was a return statement after a call to throw_exception which causes a unreachable code warning. I can see no problem by just removing that return. see http://svn.boost.org/trac/boost/ticket/1791
Speaking of unreachable code, i get some similar warnings from variant (when building in release mode):
boost\variant\detail\visitation_impl.hpp(205) : warning C4702: unreachable code boost\variant\detail\visitation_impl.hpp(180) : warning C4702: unreachable code boost\variant\detail\visitation_impl.hpp(252) : warning C4702: unreachable code boost\variant\detail\visitation_impl.hpp(280) : warning C4702: unreachable code
There are some 'should never be here at runtime:' comments in the code in question, but it would still be nice to silence the warnings 'officially'.
Thanks, Richard Webb
