--- Comment #11 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The original testcase works on trunk, although it's still possible to create
dangling references from valarray expressions by using `auto` (especially in
functions returning `auto` or `decltype(auto)` which end up returning an
expression template referring to a local valarray on the function's stack).
