--- Comment #9 from Richard Biener <rguenth at gcc dot gnu.org> ---
The original ICE means that in
inline hashval_t
external_ref_hasher::hash (const value_type *r)
{
dw_die_ref die = r->type;
hashval_t h = 0;
/* We can't use the address of the DIE for hashing, because
that will make the order of the stub DIEs non-deterministic. */
if (! die->comdat_type_p)
/* We have a symbol; use it to compute a hash. */
h = htab_hash_string (die->die_id.die_symbol);
die->die_id.die_symbol is NULL (I suppose).
I suppose the guard means that in non-LTO this _is_ a comdat type. But
LTO somehow demoted it?
We still lack a proper testcase.
