This fixes a segfault on infinite function call recursion (rather than infinite thunk recursion) by tracking the function call depth in `EvalState`. Additionally, to avoid printing extremely long stack traces, stack frames are now deduplicated, with a `(19997 duplicate traces omitted)` message. This should only really be triggered in infinite recursion scenarios. Before: $ nix-instantiate --eval --expr '(x: x x) (x: x x)' Segmentation fault: 11 After: $ nix-instantiate --eval --expr '(x: x x) (x: x x)' error: stack overflow at «string»:1:14: 1| (x: x x) (x: x x) | ^ $ nix-instantiate --eval --expr '(x: x x) (x: x x)' --show-trace error: … from call site at «string»:1:1: 1| (x: x x) (x: x x) | ^ … while calling anonymous lambda at «string»:1:2: 1| (x: x x) (x: x x) | ^ … from call site at «string»:1:5: 1| (x: x x) (x: x x) | ^ … while calling anonymous lambda at «string»:1:11: 1| (x: x x) (x: x x) | ^ … from call site at «string»:1:14: 1| (x: x x) (x: x x) | ^ (19997 duplicate traces omitted) error: stack overflow at «string»:1:14: 1| (x: x x) (x: x x) | ^ |
