--- Comment #5 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
There is:
fld_worklist_push (TYPE_MAIN_VARIANT (t), fld);
/* Do not walk TYPE_NEXT_VARIANT. We do not stream it and thus
do not and want not to reach unused variants this way. */
I believe this is the bug, we do want to walk it even if it is not streamed.
Walking it should be just more work during fld, true, but I don't see what harm
it would do. Honza?

tree ctx = TYPE_CONTEXT (t);
certainly fixes the ICE.
