--- Comment #3 from ktkachov at gcc dot gnu.org ---
I think that's when terminate_and_process_all_chains is called without any
chains having been detected. m_stores_head will not have a sensible value.
Returning early from terminate_and_process_all_chains if m_stores is empty
seems like a quick fix for this
