--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
So the odd thing is that PTA sees

      /* Nodes without a body are not interesting.  Especially do not
         visit clones at this point for now - we get duplicate decls
         there for inline clones at least.  */
      if (!node->has_gimple_body_p () || node->inlined_to)
        continue;
      node->get_body ();

(gdb) p node->debug ()

but

  /* Return true when callgraph node is a function with Gimple body defined
     in current unit.  Functions can also be define externally or they
     can be thunks with no Gimple representation.

     Note that at WPA stage, the function body may not be present in memory. 
*/
  inline bool has_gimple_body_p (void);

where I assume that this means the current _LTRANS_ unit has the body
defined.

The other odd thing is that the node has ->used_from_other_partition false.

Full initial symtab:

oddly enough symbol and alias are in different partitions?

Honza - is this a PTA bug (need to check in_other_partition?) or a IPA bug?
