Affected: 7.x-1.0 · 7.x-1.0 alpha1 · 7.x-1.0 alpha2 · 7.x-1.0 alpha3 · 7.x-1.0 alpha4 · 7.x-1.0 beta2 · 7.x-1.1 beta1 · 7.x-1.x dev

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.x-1.0

1. Check installed version

apt-cache policy gcc || rpm -q gcc || gcc --version

2. No fixed release: DOWNGRADE to a release before 7.x-1.0 (Debian / Ubuntu)

apt-cache madison gcc sudo apt install gcc=<VERSION_BEFORE_7.x-1.0> sudo apt-mark hold gcc

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list gcc sudo dnf downgrade gcc-<VERSION_BEFORE_7.x-1.0> sudo dnf versionlock add gcc

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
