error[E0309]: the associated type `<Self as SomeTrait<'a>>::Type1` may not live long enough
  --> $DIR/wf-trait-associated-type-region.rs:9:18

LL | trait SomeTrait<'a> {
   |                 -- the associated type `<Self as SomeTrait<'a>>::Type1` must be valid for the lifetime `'a` as defined here...
LL |     type Type1;
LL |     type Type2 = &'a Self::Type1;
   |                  ^^^^^^^^^^^^^^^ ...so that the reference type `&'a <Self as SomeTrait<'a>>::Type1` does not outlive the data it points at

help: consider adding an explicit lifetime bound
