    vala: Set is_yield_expression in async context when chaining up to async base ctor
    
    vala-CRITICAL **: vala_member_access_get_inner: assertion 'self != NULL' failed
    vala-CRITICAL **: vala_member_access_get_member_name: assertion 'self != NULL' failed
    
    Avoid these spurious criticals and trigger the currently expected error.
