Is emacs' gc recursive? Will it crash if there is > a long enough list? Yes, GC is very recursive, although it shouldn't cause stack overflow with "usual" data structure. No, a long list shouldn't cause such deep recursion, but a deeply-recursive list or some other recursive data structure could, if the depth is unusually large.
