Stack overflow in typedefs.js when generating JSON schema

[epost]

Example term:

; 'name' allows for let-binding and aliasing
(name either      (+ (var 0) (var 1)))
(name bit         (+ 1 1))
(name nibble      (* bit bit bit bit))
(name bitOrNibble (either bit nibble))

This is one of the example terms from the tests, also used on https://try.typedefs.com. (You can reproduce the error there; have a look at the console.)

Update: this is reproducible for me using Chrome on Mac, but not using Firefox on Mac.
