let foo: T = Foo((1u32, 1u32));
let x = move || {
let derive = move || {
let Foo((a, b)) = foo;
};
};
}

Research direction
Reproduce the ICE with the reduced upvar.rs example using the shown rustc command and inspect compiler/rustc_mir_build/src/build/expr/as_place.rs around line 261. Trace how the nested move closures and type alias impl Trait reach upvar resolution; done means this input no longer causes an internal compiler error.
