From: "jaruga (Jun Aruga)" Date: 2022-05-14T07:12:32+00:00 Subject: [ruby-core:108549] [Ruby master Bug#18781] MJIT tests failing with Ubuntu focal with gcc-11 and some flags Issue #18781 has been reported by jaruga (Jun Aruga). ---------------------------------------- Bug #18781: MJIT tests failing with Ubuntu focal with gcc-11 and some flags https://bugs.ruby-lang.org/issues/18781 * Author: jaruga (Jun Aruga) * Status: Open * Priority: Normal * Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN ---------------------------------------- I find some MJIT tests failing in `test/ruby/test_jit.rb` and `test/ruby/test_rubyvm_jit.rb` on gcc 11 on Ubuntu focal on the latest master branch `708e839dee57bc5ef8f5b21fb4fa620e89caeb52` on CI. [Here](https://github.com/ruby/ruby/runs/6430518723#step:18:288) is the CI log on [another PR](https://github.com/ruby/ruby/pull/5900#issuecomment-1126570348) on GitHub Actions - `.github/workflows/compilers.yml` on Ubuntu focal. The used configure options are `./configure --enable-shared --with-gcc="gcc -O2 -fcf-protection -Wl,-z,now"`. I was able to reproduce it on my local Fedora 35 too. Here is the steps. For convenience, I would just show one test failure. ``` $ gcc --version gcc (GCC) 11.2.1 20220127 (Red Hat 11.2.1-9) Copyright (C) 2021 Free Software Foundation, Inc.
