You are right,
gcc-12 build pass.
gcc-8 build failed.


If you want to reproduce with gcc-8 you may follow these steps.

# To install tuxmake to your home directory at ~/.local/bin:
# pip3 install -U --user tuxmake
#
# Or install a deb/rpm depending on the running distribution
# See https://tuxmake.org/install-deb/ or
# https://tuxmake.org/install-rpm/
#
# See https://docs.tuxmake.org/ for complete documentation.
# Original tuxmake command with fragments listed below.
# tuxmake --runtime podman --target-arch arm64 --toolchain gcc-8
--kconfig defconfig


tuxmake --runtime podman --target-arch arm64 --toolchain gcc-8
--kconfig https://storage.tuxsuite.com/public/linaro/lkft/builds/2TN3A8EaWQJAcOYnbXZnkb7D3H7/config
