--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Fixed in GCC 8.0. C++20 added support for this feature and GCC enables it a=
s an
extension for C++11+ with a warning:
<source>:1:19: warning: default member initializers for bit-fields only
available with -std=3Dc++2a or -std=3Dgnu++2a
 class C { bool x:1=3Dfalse; };
                   ^
ASM generation compiler returned: 0
