  I have a reservation about one of the comments. I will fix the rest of the issues in a new version of the patch (probably tomorrow).

For this patch, I could indeed just return the correct SVal. However, here I am also preparing the ground for the second patch. For that, I need the value to be stored in the state, so that I can later query them when I run through the temporary destructor branches. So, in theory I could do the binding only when cfg-temporary-dtors is true, but I'm not sure if that's worth the increased code complexity.
