That wasn't my intent, and I apologize if my wording somehow implied that. I was only talking about the particular crash you reported. Any other crash should be analyzed separately, and the conclusion could very well be different. > THanks.

It is strange you cannot trigger the stack-overflow protection in your build, though. If you write a trivial infinite-recursion Lisp function, and then run it after lifting max-lisp-eval-depth and max-specpdl-size to the largest positive number, don't you see what I saw on my system?
