Crazy VS2010 Express error

[Disch]

So check this out:

The code in question:

    // support function.  Gets the point of a given exit.  If 'actual' is false, the point will
    //   be "pushed inside" the bounding box.  If 'actual' is true, it will be the point on the actual
    //   block boundary (before padding)
    const auto getPoint = [&](int p, bool actual) -> sf::Vector2f
    {
        float adj = actual ? c_BoundBoxPadding : 0;
        switch(p)
        {
        case U:     return sf::Vector2f( (box.l + box.r) / 2,  box.u - adj        );   // <- line 91
        case D:     return sf::Vector2f( (box.l + box.r) / 2,  box.d + adj        );
        case L:     return sf::Vector2f(  box.l - adj       , (box.u + box.d) / 2 );
        case R:     return sf::Vector2f(  box.r + adj       , (box.u + box.d) / 2 );
        case K:     return sf::Vector2f( (box.l + box.r) / 2, (box.u + box.d) / 2 );
        default:    throw std::logic_error("Error in map generation!  invalid 'p' value sent to getPoint");
        }
    };

Any ideas how this could be "simplified"?

XD

EDIT:
I guess I could try getting rid of the lambda, make it a global function and pass the 'box' to it as an argument.....
