module object;
enum Foo {}
------
-------
$ /usr/x86_64-pc-linux-gnu/gcc-bin/14/gdc repro.d -freport-bug

gdc-13 works:
-------
$ /usr/x86_64-pc-linux-gnu/gcc-bin/13/gdc repro.d
repro.d:2:1: error: enum ‘object.Foo’ enum ‘Foo’ must have at least one member
2 | enum Foo {}
| ^
-------
And so do dmd and ldc2.
