Interpreter crash: incorrect signature of recursive function

[bkDJ]

Minimum repro:

Foo ← |3 ⟨◌|Foo -1⟩±.⊙⊙∘
Foo 2 0 0

Changing the signature to |3.2 solved it, but the above code on branch main commit e3ccd04b yields:

The application panicked (crashed).
Message:  slice index starts at 2 but ends at 1
Location: /private/tmp/rust-20240215-5649-scngkd/rustc-1.76.0-src/library/alloc/src/vec/mod.rs:2084

Backtrace omitted.

Run with RUST_BACKTRACE=1 environment variable to display it.
Run with RUST_BACKTRACE=full to include source snippets.
