Issue #18073 has been updated by jeremyevans0 (Jeremy Evans). Status changed from Open to Closed These failures look related to MJIT, which has been removed. ---------------------------------------- Bug #18073: test/ruby/test_jit.rb: "error: invalid use of '__builtin_va_arg_pack ()'" on Ruby 2.7.4 on gcc 4.8.5 https://bugs.ruby-lang.org/issues/18073#change-104347 * Author: jaruga (Jun Aruga) * Status: Closed * Priority: Normal * Backport: 2.6: UNKNOWN, 2.7: REQUIRED, 3.0: DONTNEED ---------------------------------------- I hit the following JIT test failures causing the following error on v2_7_4 tag (Ruby 2.7.4) with gcc 4.8.5 on RHEL 7. The tests work on Ruby 2.7.3 and also works on Ruby 3.0.2. ``` /mnt/git/ruby/ruby/.ext/include/x86_64-linux/rb_mjit_min_header-2.7.4.h: In function 'sprintf': /mnt/git/ruby/ruby/.ext/include/x86_64-linux/rb_mjit_min_header-2.7.4.h:442:3: error: invalid use of '__builtin_va_arg_pack ()' return __builtin___sprintf_chk (__s, 2 - 1, ^ ``` ``` $ which gcc /usr/bin/gcc $ gcc --version gcc (GCC) 4.8.5 20150623 (Red Hat 4.8.5-39) Copyright (C) 2015 Free Software Foundation, Inc.
