Why do you think it is similar? It crashes in a different place, and if in David's case there was a hypothesis that FACE_FROM_ID returned a null pointer, in your case I see that all face arguments are non-NULL. What am I missing? Btw, David's crash was in Emacs 23.1.95, so I'm pretty sure the bidi merge has nothing to do with it. Yours is with the trunk version, right? > I can reproduce it reliably, but it depends on something in my .emacs, > so I cannot give a recipe right now. Please do try to give a reproducible recipe. Btw, what were you doing when it crashed? The backtrace seems to tell that Emacs was displaying a message in the echo area (during an Edebug session?), and that there were characters in the message area that used compositions, is that right? If so, what was the text of the message? If the crash happens even with normal ASCII characters in the echo area, I'd prefer to see a backtrace of that variant. Thanks.
