--- Comment #4 from Marek Polacek <mpolacek at gcc dot gnu.org> ---
We crash in cxx_eval_store_expression.  *valp for 'str', the VAR_DECL, used=
 to
be {.str=3D""} so in the !refs->is_empty () loop we'd go to the if (TREE_CO=
DE
(*valp) =3D=3D STRING_CST) branch when processing the .str initializer.  Bu=
t now
*valp is {.str=3DVCE<char[8]>("")} so we crash on
no_zero_init =3D CONSTRUCTOR_NO_CLEARING (*valp);

So far it seems to me that we just need to strip the location wrapper.=
