`OpenSSL::TestPKey#test_s_generate_parameters` random failures

[voxik]

Testing with Ruby 3.1, the Ruby test suite sometimes fails with the following error:

  1) Failure:
OpenSSL::TestPKey#test_s_generate_parameters [/builddir/build/BUILD/ruby-3.1.0/test/openssl/test_pkey.rb:44]:
RuntimeError expected but nothing was raised.

Is this with OpenSSL 3.0? Your comment in 2021-11 on the same failure: https://github.com/ruby/openssl/pull/399#issuecomment-963935021

I haven't been able to reproduce it locally.

Yes, Ruby 3.1 with OpenSSL 3.0

Your comment in 2021-11 on the same failure: #399 (comment)

Ah, right, sorry, I have already forgotten about that remark. But at that time, I was not sure it is not issue with the patches backported to Ruby 3.0.2. Now it is with Ruby 3.1, so is likely not my fault (although who knows :wink:)

I haven't been able to reproduce it locally.

Unfortunately, it fails just from time to time and I don't have better reproducer at hand :/

Running the test file repeatedly was enough to reproduce it: while ruby -Ilib -Itest/openssl test/openssl/test_pkey.rb; do :; done

It turned out to be an issue in the current OpenSSL 3.0.x. https://github.com/openssl/openssl/pull/19314
