Building with llvm18, I got following stack trace:

LLVM 18? Julia master doesn't even support LLVM 17 yet, v1.11 only supports LLVM 16. But I take you're trying to build Julia with an external and unsupported llvm version, which based on googling the error message

LLVM ERROR: inconsistency in registered CommandLine options

is very likely the cause of your problem.

By "llvm18", I wanted to say that I built julia with clang18. I always used llvm shipped with julia.
But I looked into the wrong log file, and the above error message was built by gcc13. (building julia with clang on FreeBSD has the same problem as #52067 until recent FreeBSD-current. I will try it later)

I found this conversation. It is rather old but describes the problem I encountered.

• The problem seems to be caused by initCommonOptions() invoked many times. It is in libLLVMSupport.a (from deps/srccache/llvm-julia-16.0.6-2/llvm/lib/Support/CommandLine.cpp)
• libLLVM-16jl.so links all the static LLVM libraries in us/lib/.
• libjulia-internal.so links libLLVMSupport.a and libLLVMTargetParser.a (via RT_LLVM_LIBS in src/Makefile)
• libjulia-codegen.so links all the static LLVM libraries, libjulia-internal.so and libLLVM-16jl.so (via CG_RELEASE_LIBS and CG_LLVMLINK in src/Makefile)

So, there is three instance of initCommonOptions(), one in libLLVM-16jl.so, one in libjulia-codegen.so and one in libjulia-internal.so, which make initCommonOptions() called many times.
The solution I took is to remove linking of static LLVM libraries from libjulia-internal.so and libjulia-codegen.so, and link libLLVM-16jl.so to libjulia-internal.so too. As libLLVM-16jl.so links all the static LLVM libraries, the code in the three libraries may call LLVM functions while initCommonOptions() is called only once in libLLVM-16jl.so.
