I was able to procude a simple testcase:
trait Curve {}
enum E {X(Curve)}
fn main() {}

Now I see why this is wrong, it would be nice to have a proper error message for this case.

a similar case:

struct Struct {
    r: io::Reader
}

fn new_struct(r: io::Reader) -> Struct {
    Struct { r: r }
}

Can you re-test this with incoming? That particular ICE is no longer
relevant, but there may be some similar bug that occurs.

This is fixed. Added a test case in #7863 -- this can close when it lands.
