My specific issue isn't about scope, it's strictly usage of a reference. I
know for a fact that the container is not being destroyed at this specific
area of code. Below is what I'm actually doing:

    static Texture const* FindTexture( std::string const& textureId,
TextureContainer const& textures )
    {
        TextureContainer::const_iterator it = textures.find( textureId );
        if( it == textures.end() )
        {
            /// @todo Throw an exception here?
            assert(0);
        }

        return it->second;
    }

And since the error message is so long I've placed that in a text file and
attached that to this email. If there's anything else I can provide I'd be
happy to. I have no leads on what this error could mean. I wish it wasn't so
cryptic.
