analyzer fuzz crash: old style function typed formal parameter with type args #38057
Description
This one is interesting because it is technically valid dart code!
class C {
Function() f;
C(this.f<T>());
}This is technically a valid field initializer for f that constrains the type from Function() to Function<T>(). @leafpetersen if he cares to confirm/comment.
However this is the old way, and the new way works (class C { Function() f; C(Function<T> this.f); }). So this is an extremely edge case language feature.
