// |jit-test| error: InternalError

// This tests that attempting to perform ModuleDeclarationInstantation a second
// time after a failure throws an error. Doing this would be a bug in the module
// loader, which is expected to throw away modules if there is an error
// instantiating them.
//
// The first attempt fails becuase module 'a' is not available. The second
// attempt fails because of the previous failure (it would otherwise succeed as
// 'a' is now available).
