I didn’t pass wide int afaik. So whatever the default is. I believe it has to do with posframe. I use both flycheck posframe and company posframe. If I disable the flycheck one I do not get crashes. It’s possible that they are both doing frame manipulation that is more frequent and new, which is exposing these. I believe that new package is more why this is happening now.

Then I don't understand: you said this started happening only very recently, but I could see no related changes on emacs-26. Is your build --with-wide-int, per chance? Can you try bisecting?
