Stack overflow due to recursion with const generics #93581

Open cameron1024 opened 2 years ago

cameron1024 commented 2 years ago

I ran into this while trying to do arithmetic in the type system. This is the most minimal example that could repro the issue. Doing more "simple" arithmetic works fine.

Given the following code: 

use std::marker::PhantomData;

const ANSWER: i32 = Fib::<I32<4>>::VALUE;  // gives weird output
// const ANSWER: i32 = If::<Eq<I32<5>, I32<5>>, I32<4>, I32<6>>::VALUE;  // correctly prints 4
// const ANSWER: i32 = Add::<I32<5>, I32<5>>::VALUE;  // correctly prints 10
// const ANSWER: i32 = I32::<5>::VALUE;  // correctly prints 5

fn main() {
    println!("{ANSWER}");
}

trait Expr<T> {
    const VALUE: T;
}

struct Add<A: Expr<i32>, B: Expr<i32>>(PhantomData<A>, PhantomData<B>);
struct Mul<A: Expr<i32>, B: Expr<i32>>(PhantomData<A>, PhantomData<B>);
struct Sub<A: Expr<i32>, B: Expr<i32>>(PhantomData<A>, PhantomData<B>);

struct Eq<A: Expr<i32>, B: Expr<i32>>(PhantomData<A>, PhantomData<B>);
struct If<C: Expr<bool>, A: Expr<i32>, B: Expr<i32>>(
    PhantomData<A>,
    PhantomData<B>,
    PhantomData<C>,
);

struct I32<const N: i32>;

impl<A: Expr<i32>, B: Expr<i32>> Expr<i32> for Add<A, B> {
    const VALUE: i32 = A::VALUE + B::VALUE;
}
impl<A: Expr<i32>, B: Expr<i32>> Expr<i32> for Mul<A, B> {
    const VALUE: i32 = A::VALUE * B::VALUE;
}
impl<A: Expr<i32>, B: Expr<i32>> Expr<i32> for Sub<A, B> {
    const VALUE: i32 = A::VALUE - B::VALUE;
}

impl<A: Expr<i32>, B: Expr<i32>> Expr<bool> for Eq<A, B> {
    const VALUE: bool = A::VALUE == B::VALUE;
}

impl<A: Expr<i32>, B: Expr<i32>, C: Expr<bool>> Expr<i32> for If<C, A, B> {
    const VALUE: i32 = if C::VALUE { A::VALUE } else { B::VALUE };
}

impl<const N: i32> Expr<i32> for I32<N> {
    const VALUE: i32 = N;
}

// fibonacci

struct Fib<T: Expr<i32>>(PhantomData<T>);

impl<N: Expr<i32>> Expr<i32> for Fib<N> {
    const VALUE: i32 = If::<
        Eq<I32<0>, N>,
        I32<1>,
        If<Eq<I32<1>, N>, I32<1>, Add<Fib<Sub<N, I32<1>>>, Fib<Sub<N, I32<2>>>>>,
    >::VALUE;
}

Ideally the output should look like: It should compile without errors

This happens on stable 1.58 as well as on the latest nightly (1.60.0 2022-01-26) I've added a few similar examples that don't cause the same error, only the Fibonacci one would cause it

This problem still exists with stable rustc 1.61.0 and 1.63.0-nightly (ee160f2f5 2022-05-23).

It seems the stack overflow problem happened caused by probably infinite recursion of nested calls when compiling the test program. Tried increasing the stack size with "RUST_MIN_STACK=419430400 rustc main.rs" and the problem remains.

Using rust-gdb, we can see a very deep function calling stack (depth was 78426 at the time when segmentation fault happened):

yanchen4791 commented 2 years ago

The recursive call to Fib<> in impl for Fib caused the infinite recursion in rustc_middle::ty::relate::TypeRelation path:

struct Fib<T: Expr<i32>>(PhantomData<T>);

impl<N: Expr<i32>> Expr<i32> for Fib<N> {
    const VALUE: i32 = If::<
        Eq<I32<0>, N>,
        I32<1>,
        If<Eq<I32<1>, N>, I32<1>, Add<Fib<Sub<N, I32<1>>>, Fib<Sub<N, I32<2>>>>>,
    >::VALUE;
}

Tested by taking out the recursive calls in Fib, the problem goes away.

I ran into this while trying to do arithmetic in the type system.

...I must say, there are more computationally efficient Turing tapes.
