The following bug has been logged on the website: Bug reference: 17965 Logged by: Jingtang Zhang Email address: mrdrivingduck@gmail.com PostgreSQL version: 14.8 Operating system: CentOS 7 Description: Hi~ PG hackers. Recently I meet up this core dump on latest REL_14_STABLE branch, while executing `make check` under `contrib/ltree`. According to the stack trace, it is from libLLVM13.so. I'm not so sure about whether it is a bug of LLVM or PostgreSQL. Any ideas? And what is the recommended version of LLVM to use now?
