RGWSwiftWebsiteHandler::serve_errordoc() calls rgw_process_authenticated(), and thus - indirectly - rgw_build_object_policies(). Unfortunately, the function is not intended to be called twice on same req_state as its object_acl and bucket_acl members are raw pointers, not unique_ptrs and the function doesn't free memory on its own.
