I am using Ruby 2.6.3 in my project. Suddenly my application raises segmentation fault issue, I have tried the solution mentioned in https://bugs.ruby-lang.org/issues/18555#note-6 the above issue, but it doesn't solve my problem. I have attached log of the error.

This is not a segmentation fault (SIGSEGV), it's an illegal instruction crash (SIGILL). Considering it occurs in /usr/local/lib/ruby/2.6.0/openssl/buffering.rb, this is likely an issue either in the ruby openssl extension or in openssl itself. Could possibly be related to missing BTI support in the version of openssl you are using, assuming your processor supports BTI.

In any case, Ruby 2.6.3 is end-of-life and no longer supported. Please upgrade to a supported version of Ruby (3.3, 3.2, or 3.1).
