--- Comment #6 from Nathaniel Shead <nshead at gcc dot gnu.org> ---
Improved the diagnostic for GCC 16; the testcase in comment #2 now says:
main.cpp: In function ‘int foo(MainWindow)’:
main.cpp:7:13: error: invalid use of incomplete type ‘struct User’
7 | return m.u->value;
| ^~
main.cpp:1:8: note: forward declaration of ‘struct User’
1 | struct User;
| ^~~~
In module User, imported at main.cpp:5:
user.cpp:2:15: note: ‘struct User@User’ has a definition but does not
correspond with ‘struct User’ because it is attached to a different module
2 | export struct User {
| ^~~~
