--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Confirmed, also started to ICE in GCC 9.4.0.
Note the full command line needed to get the ICE is:
-fno-elide-constructors -O2 -std=3Dc++14

using -std=3Dc++11 the code does not ICE.
Also note in GCC 9.3 and before -fno-elide-constructors  -std=3Dc++14 rejec=
ts the
code.=
