    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.
