ICE: node_id_to_type: no type for node unknown node (id=N)

[alexcrichton]

For this program:

pub struct Foo<T> {
  data: T,
}

fn foo<T>(Foo{data}: Foo<T>) {
}

fn main() {
}

You receive this output:

$ rustc foo.rs                                           
error: internal compiler error: node_id_to_type: no type for node `unknown node (id=11)`

I am... surprised this even parses.

[alexcrichton]

Should it not be possible to have destructing assignment for arguments?

[nikomatsakis]

Oh, you are correct. I didn't realize that was a pattern, but of course it is.

This was fixed in #5039
