Issue #20520 has been updated by vo.x (Vit Ondruch). I'll try to workaround this by `--disable-fortify-source`, I hope it won't have another side effects. ---------------------------------------- Bug #20520: _FORTIFY_SOURCE=3 is not correctly respected https://bugs.ruby-lang.org/issues/20520#change-108590 * Author: vo.x (Vit Ondruch) * Status: Open * ruby -v: ruby 3.3.1 (2024-04-23 revision c56cd86388) [aarch64-linux] * Backport: 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- In Fedora, we are using following compilation options: ~~~ + CFLAGS='-O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe -Wall -Werror=format-security -Wp,-U_FORTIFY_SOURCE,-D_FORTIFY_SOURCE=3 -Wp,-D_GLIBCXX_ASSERTIONS -specs=/usr/lib/rpm/redhat/redhat-hardened-cc1 -fstack-protector-strong -specs=/usr/lib/rpm/redhat/redhat-annobin-cc1 -mbranch-protection=standard -fasynchronous-unwind-tables -fstack-clash-protection -fno-omit-frame-pointer -mno-omit-leaf-frame-pointer ' ~~~ Please note that as of recently, there is included `_FORTIFY_SOURCE=3`.
