Describe the bug

nix-repl> :p let a = _: { a = a a; }; in a {}
{ a = { a = ..... { a = zsh: segmentation fault

Steps To Reproduce

Try the above in nix repl but not on x86_64-linux where it works.

If you don't want to have the printing code involved in the overflow, do something with seq for example.

Expected behavior

• no crash
• an error message saying stack overflow
• ideally a Nix stack trace: Impossible to trace error: stack overflow (possible infinite recursion) #6361

nix-env --version output

2.16.0pre20230428_89d3cc5

x86_64-darwin, aarch64-darwin, aarch64-linux

Additional context

Workaround: when nix crashes on mac, try evaluating the same thing on linux. You might learn that it is indeed a stack overflow, ruling out another kind of bug with a fairly high degree of certainty.
However, even in this case, it's not very actionable because of the

• Lack of a trace: Impossible to trace error: stack overflow (possible infinite recursion) #6361
