--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I don't see how my change could be related, neither of the two functions I've
touched is ever called on the testcase.
The ICE goes away with -fno-new-ttp-matching, so I think it is much more likely
this is caused by r243871.
The ICE is because dwarf2out is invoked on a RECORD_TYPE that is not
instantiated, at least its FIELD_DECL has been created by:
23578 /* Remove constructors and such from TYPE, now that we
23579 know it is an anonymous aggregate. */
23580 fixup_anonymous_aggr (type);
23581 /* And make the corresponding data member. */
23582 decl = build_decl (decl_spec_token_start->location,
23583 FIELD_DECL, NULL_TREE, type);
23584 /* Add it to the class. */
23585 finish_member_declaration (decl);
in parser.c.
