I would like to backport it separately. The list of versions affected is different and moreover I do not have the problem reproducible. I have tried devtoolset-8-gcc-8.3.1-3.2.el7.x86_64 (CentOS-7) and gcc-8.3.0.tar.xz (rebuilt from source). I have tried to build this branch https://github.com/jankratochvil/jdk17u-dev/tree/8324243 .
