--- 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 ()

/* Return true when callgraph node is a function with Gimple body defined

can be thunks with no Gimple representation.

*/
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.

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?
