Just for reference here is the ICE that is produced:
```

same_comdat_group list.

Confirm as a bug.  It's still present in the mainline.

What is happening here is that multiple decls for f is getting in the way.  
Either we have to look at the 
DECL_UID or change the C++ front-end to only have one decl for f.
