nix eval segmentation fault on long line (`nix eval nixpkgs#lispPackages_new.sbclPackages`)

[hraban]

Describe the bug

Nix tool segfaults when printing a large set.

Steps to reproduce

$ nix eval  nixpkgs#lispPackages_new.sbclPackages
Segmentation fault: 11

Another example:

$ nix repl
(import <nixpkgs> {}).lispPackages_new.sbclPackages

... outputs a lot, then:

Segmentation fault: 11
$

Same if I clone nixpkgs locally and do import ./. {}, instead.

Expected behavior

A very very long output line.

You're right thank you, that makes sense. Thanks, I'm still new to the whole thing.
