I think I have a fix for this one. I plan to check it in soon, maybe
today, as it's been around for quite a while.

I believe I saw these with ASAN as well. I think what happens here is
that the pretty-printer code creates a value from a virtual base class
slice of an object, but doesn't "inflate" it to the full object,
resulting in some out-of-bounds reads.
