// RUN: %target-swift-frontend -typecheck %s -verify -verify-ignore-unknown

// FIXME: This should produce a diagnostic with a proper
// source location. Right now, we just get three useless errors:

// <unknown>:0: error: type of expression is ambiguous without a type annotation
// <unknown>:0: error: type of expression is ambiguous without a type annotation
// <unknown>:0: error: type of expression is ambiguous without a type annotation

// The actual problem is the type of the subscript declaration is wrong.
