--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
This used to be rejected before r260272 with:
pr92423.C: In function ‘int main()’:
pr92423.C:15:49: error: use of deleted function ‘Foo::Foo(const Foo&)’
   const auto& my_foo = (true ? base_foo : throw "");
                                                 ^~
pr92423.C:4:3: note: declared here
   Foo (const Foo& x) = delete;
   ^~~
starting with that would call the dtor twice, and finally since r274550 aka
PR90393 calls dtor just once.
I think the g++.dg/expr/cond16.C testcase is sufficiently similar to this one
that it isn't worth adding another one.
