Following is my observation: There are 24 threads and all are doing the thread local memory cleanup as part of garbage collection process. Thread 23 especially is reporting sigsegv during the GC process. Thread 1 is SIGABORT due to the corruption at Thread 23 root [ / ]# ruby --version ruby 2.7.3p183 (2021-04-05 revision 6847ee089d) [x86_64-linux] root [ / ]# gem --version 3.1.6 -- https://bugs.ruby-lang.org/
