Issue #19386 has been updated by jaruga (Jun Aruga). I debugged the issue on the latest master branch `47b66a5acd1511089ac9585371d93e1b5ea07232` on the RHEL 9 instance. I installed the following RPM packages to compile and debug. The gdb asked the following debuginfo RPM packages are missing. So, I installed these ones. ``` $ sudo dnf install gdb $ sudo dnf install ruby $ sudo dnf debuginfo-install glibc-2.34-40.el9_1.1.x86_64 gmp-6.2.0-10.el9.x86_64 libgcc-11.3.1-2.1.el9.x86_64 libxcrypt-4.4.18-3.el9.x86_64 zlib-1.2.11-35.el9_1.x86_64 $ sudo dnf debuginfo-install openssl-libs-3.0.1-43.el9_0.x86_64 ``` I compiled the Ruby with the following flags. ``` $ ./autogen.sh $ optflags=-O0 debugflags="-g3 -ggdb3 -gdwarf-4" \ ./configure \ --prefix=$HOME/.local/ruby-47b66a5acd-O0 \ --enable-shared $ make ``` Then I confirmed the stuck or coredump happened with the command below. ``` [jaruga@rhel9 ruby]$ make test-all V=1 TESTS="-v test/openssl/test_hmac.rb -n OpenSSL::TestHMAC#test_dup" exec ./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems "./test/runner.rb" --ruby="./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems" - -excludes-dir=./test/excludes --name=!/memory_leak/ -v test/openssl/test_hmac.rb -n OpenSSL::TestHMAC#test_dup Run options: --seed=25634 "--ruby=./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems" --excludes-dir=./test/excludes --name=!/memory_leak/ -v -n OpenSSL::TestHMAC#test_dup # Running tests: [1/0] OpenSSL::TestHMAC#test_dup = 0.00 s Finished tests in 0.025968s, 38.5083 tests/s, 154.0333 assertions/s. 1 tests, 4 assertions, 0 failures, 0 errors, 0 skips ruby -v: ruby 3.3.0dev (2023-01-27T11:07:06Z master 47b66a5acd) [x86_64-linux] ^Cmake: *** [uncommon.mk:850: yes-test-all] Interrupt ``` Here is the gdb backtrace. ``` [jaruga@rhel9 ruby]$ gdb -q -ex "set breakpoint pending on" --args ./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems "./test/runner.rb" --ruby="./miniruby -I./lib -I. -I.ext/common ./tool/runruby.rb --extout=.ext -- --disable-gems" --excludes-dir=./test/excludes -v test/openssl/test_hmac.rb -n OpenSSL::TestHMAC#test_dup (gdb) b main ...<snip>...

But it stuck with openssl tests. see http://rubyci.s3.amazonaws.com/rhel9/ruby-master/log/20230127T003004Z.fail.h... I did bisect this issue. This issue caused by https://github.com/ruby/ruby/blob/master/test/openssl/test_hmac.rb#L23 ``` def test_dup h1 = OpenSSL::HMAC.new("KEY", "MD5") h1.update("DATA") h = h1.dup assert_equal(h1.digest, h.digest, "dup digest") end ``` Stuck is happened after running this test. /cc @vo.x @jaruga @rhenium -- https://bugs.ruby-lang.org/
