--- Comment #8 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
This seems to be bug in ipa-cp, it redirect edge from thunk to clone of the
function thunk is associated with.
Old value = (cgraph_node *) 0x7ffff6c5fb88
New value = (cgraph_node *) 0x7ffff6c5f668

I believe it is bug somewhere in logic skipping thunks. Martin, this is
probably yours.
