That is a large > structure; what parts of it remain constant? The address of the structure remains constant (that is, display_line is called with the same pointer). I don't know if this is expected to change or not. I didn't actually compare the contents between calls. >> I'm attaching the output of *it in the email, hoping it might be useful. > > Thanks, but it by itself doesn't help enough. I need to see the text > that Emacs is trying to display, at least. This is hard to do. I tried to simply copy the text to another buffer in trying to reproduce the problem, but I couldn't. It might be due some overlays or properties. Is there some way to conveniently dump the entire buffer state to a file so we can debug this by reloading the content without having the mail client in the way? There's a lot of customization in the way which is making this harder than it should be.
