[Message part 1 (text/plain, inline)]

Hi,

Package: emacs
Version: 28.2

I received the following stack trace from my emacs crashing. This is not a consistent error, and so I have not been able to reproduce it. I thought that this might be useful to someone here. Whatever else goes on, I suspect that emacs should not itself crash as a result, and that indicates a bug in emacs. I know that this is a port and not the standard GNU Emacs; still, I thought maybe what’s going on here would be common across both versions.
