(finish_struct_1): Call check_flexarrays. * decl.c (compute_array_index_type): Distinguish flexible array members from zero-length arrays. (grokdeclarator): Reject flexible array members in unions. Avoid rejecting members of incomplete types that are flexible array members. * error.c (dump_type_suffix): Handle flexible array members with null upper bound. * init.c (perform_member_init): Same. * pt.c (instantiate_class_template_1): Allow flexible array members.

(output_constructor_regular_field): Same. (output_constructor): Set min_index to integer_zero_node rather than null when a type has no domain to avoid crashing later.
I think this caused PR68932 - FAIL: obj-c++.dg/property/at-property-23.mm -fgnu-runtime (internal compiler error)
