| // `eii` expands to, among other things, `macro eii() {}`. |
| // If we have two eiis named the same thing, we have a duplicate definition |
| // for that macro. The compiler happily continues compiling on duplicate |
| // definitions though, to emit as many diagnostics as possible. |
| // However, in the case of eiis, this can break the assumption that every |
| // eii has only one default implementation, since the default for both eiis will |
| // name resolve to the same eii definiton (since the other definition was duplicate) |
| // This test tests for the previously-ICE that occurred when this assumption |
| // (of 1 default) was broken which was reported in #149982. |
