Expected Behavior

this piece of code compiles

package test

import "core:fmt"

Foo :: struct($T: typeid) {
        val: T,
        a:   Foo(T),
        b:   Foo(T),
}

make_foo :: proc($T: typeid, v: T) -> Foo(T) {
        return new_clone(Foo{val = v})
}

main :: proc() {
  f := make_foo(int, 1)
}

Current Behavior

compiler hangs indefinitely

Steps to Reproduce

1. paste the code
2. odin build .
3. hangs indefinitely

It is a bug, but the code as provided wasn't going to compile because Foo incorporating itself is a cycle.
This does work:

package test

import "core:fmt"

Foo :: struct($T: typeid) {
	val: T,
	a:   ^Foo(T), // Can't be `Foo(T)` because a struct can't contain itself.
	b:   ^Foo(T),
}

make_foo :: proc($T: typeid, v: T) -> ^Foo(T) { // `new_clone` returns a pointer
	return new_clone(Foo(T){val = v})       // `Foo{val = v}` had to become `Foo(T){val = v}`
}

main :: proc() {
	f := make_foo(int, 1)
	fmt.println(f) // &Foo($T=int){val = 1, a = <nil>, b = <nil>}
}

Having said that, it doesn't hang for me so much as fail with a stack overflow.
