[Boost-users] alignment error with make_shared?

Subject: [Boost-users] alignment error with make_shared?
From: Kenny Riddile (kfriddile_at_[hidden])

m_meshes is a std::vector< boost::shared_ptr<const Mesh> > in the code 
below, and Mesh is constructible from a const std::string&

BOOST_FOREACH( const std::string& fileName, meshFiles )
{
     m_meshes.push_back( boost::make_shared<Mesh>(fileName) );
}

Using make_shared here gives me the following error, while explicitly 
constructing a shared_ptr does not.  Mesh isn't defined with 
__declspec(align('16')), but I believe it owns a member that is.  Am I 
doing something wrong or is this a known limitation of make_shared? 
Also, I am using MSVC9 if that wasn't obvious.
