rustc segfaults when evaluating certain recursive trait implementations

[JackStade]

Code

// at lower recursion limits the recursion limit is reached before the bug happens
#![recursion_limit = "2000"]

// this will try to calculate 3↑↑3=3^(3^3)
type Test = <() as Op<((), ()), [[[(); 0]; 0]; 0], [[[(); 0]; 0]; 0], [[[[(); 0]; 0]; 0]; 0]>>::Result;

use std::default::Default;

fn main() {
    // force the compiler to actually evaluate `Test`
    println!("{}", Test::default());
}

trait Op<X, A, B, C> {
    type Result;
}

// this recursive function defines the hyperoperation sequence,
// a canonical example of the type of recursion which produces the issue
// the problem seems to be caused by having two recursive calls, the second
// of which depending on the first
impl<
    X: Op<(X, Y), A, [B; 0], [C; 0]>,
    Y: Op<(X, Y), A, X::Result, C>,
    A, B, C,
> Op<(X, Y), A, [[B; 0]; 0], [C; 0]> for () {
    type Result = Y::Result;
}

// base cases
impl<X, A, B> Op<X, A, B, ()> for () {
    type Result = [B; 0];
}

impl<X, A> Op<X, A, [(); 0], [(); 0]> for () {
    type Result = [A; 0];
}

impl<X, A, C> Op<X, A, [(); 0], [[C; 0]; 0]> for () {
    type Result = A;
}

This is the simplest example I could find where the trait could evaluation could actually finish in theory. A simpler example which would loop infinitely is this:

#![recursion_limit = "2000"]

trait Foo<X, A, B> {
    type Result;
}

impl<
    X: Foo<(X, Y), ((A, B), C), D>, 
    Y: Foo<(X, Y), X::Result, (B, (C, D))>, 
    A, B, C, D,
> Foo<(X, Y), (A, B), (C, D)> for () {
    type Result = Y::Result;
}

impl<X, A, B> Foo<X, (A, B), ()> for () {
    type Result = (A, B);
}

impl<X, A, B> Foo<X, (), (A, B)> for () {
    type Result = (A, B);
}

// This should cause an infinite loop which gets stopped by the recursion limit
// but if the recursion limit is increased enough (~1800) then it segfaults instead
// This happens almost immediately and the compiler uses only a small amount of memory before crashing
type Test = <() as Foo<((), ()), ((), ()), ((), ())>>::Result;

use std::default::Default;

fn main() {
    println!("{}", Test::default());
}

This uses much less time and memory before crashing compared to the hyperoperation sequence example.

Meta

The bug also exists on nightly and beta, although the recursion limit needed is higher in beta. rustc --version --verbose:
