--- Comment #3 from Tom de Vries <vries at gcc dot gnu.org> ---
The test that is failing, is:
...
760       if (SSA_NAME_VAR (ssa_name) != NULL_TREE
761           && TREE_TYPE (ssa_name) != TREE_TYPE (SSA_NAME_VAR (ssa_name)))
762         {
763           error ("type mismatch between an SSA_NAME and its symbol");
764           return true;
765         }
...

For ssa-name:
...
(gdb) call debug_generic_expr (name)
A.14_21
(gdb) call debug_tree (name)
 <ssa_name 0x7ffff6351e10
    type <pointer_type 0x7ffff673abd0

The mismatch seems to be:
...
(gdb) call debug_generic_expr (name.typed.type)
integer(kind=4)[0:D.4266] *
(gdb) call debug_generic_expr (name.ssa_name.var.typed.type)
integer(kind=4)[0:D.4433] *
...
