+A lifetime name is shadowing another lifetime name. Erroneous code example:
+
+```
+struct Foo<'a> {
+ a: &'a i32,
+}
+
+impl<'a> Foo<'a> {
+ fn f<'a>(x: &'a i32) { // error: lifetime name `'a` shadows a lifetime
+ // name that is already in scope
+ }
+}
+```
+
+Please change the name of one of the lifetimes to remove this error. Example:
+
+
+```
+struct Foo<'a> {
+ a: &'a i32,
+}
+
+impl<'a> Foo<'a> {
+ fn f<'b>(x: &'b i32) { // ok!
+ }
+}
+
+fn main() {
+}
+```

A stability attribute was used outside of the standard library. Erroneous code
example:
E0491, // in type `..`, reference has a longer lifetime than the data it...
E0492, // cannot borrow a constant which contains interior mutability
E0495, // cannot infer an appropriate lifetime due to conflicting requirements
- E0496, // .. name `..` shadows a .. name that is already in scope
E0498, // malformed plugin attribute
+ E0514, // metadata version mismatch
