Error when calling an impure constructor defined in the parent class of an anonymous class

new Foo(); on a separate line does not report an error when Foo's constructor is impure or throws an exception.

However, new class() extends Foo {}; gives an error: Expression "new class extends \Foo…" on a separate line does not do anything.

In the code snippet below, uncommenting line 18-21 removes the error.
