// There are two requirements here to result in the owner of a macro being null.
// 1) There must be a configuration mismatch between a header and a file it depends on
// 2) -fmodules-local-submodule-visibility must be enabled.

// In the following example, when compiling module C, A_H has no owning module.

// RUN: %clang_cc1 -I%t -emit-module -o %t/a.pcm -fmodules %t/module.modulemap -fmodule-name=a -fmodules-local-submodule-visibility
