I see no signs of infinite recursion in the backtrace, only some quite
deep recursion. I've seen GC go as deep as 30K recursive calls to
mark_object, so that is quite normal, certainly not unheard of.

If it's infinite recursion that hits stack overflow, Emacs will crash
due to SIGSEGV, I think. Which I understand was not the case here.
