--- Comment #14 from Jan Hubicka <hubicka at gcc dot gnu.org> ---
Good, now it reproduces. The problem is that inliner removes the alias target
and it leaves the alias itself to be removed by remove_unreachable_nodes. It
however manages to crash ealrier looking if the alias shall be inlined as
called once in somewhat convoluted test whether symbol is an alias.
