Closed eddyb closed 8 years ago

eddyb commented 8 years ago 
enum E { V { x: u8 } }

fn main() {
    match (E::V { x: 0 }) {
        E::V_Typoed { .. } => {}
    }
}

Produces, on beta:

error: internal compiler error: ../src/librustc/hir/def.rs:77: path not fully resolved:
PathResolution { base_def: Enum(DefId { krate: 0, node: DefIndex(4) => E }), depth: 1 }

On stable and nightly it triggers an appropriate resolution failure error. cc @petrochenkov
