Start by reproducing commit 21cd7726af6f743cd33557fb5311babac83fab05 on Ubuntu 18.04 with the provided CMake and Make commands. Inspect the tools/clang/tools/extra/clang-doc/CMakeFiles/obj.clangDoc.dir/JSONGenerator.cpp.o target and compare the LLVM 23.1.1 failure with the reported successful LLVM 22 build. Done means the failing target compiles successfully or the supported build limitation is clearly established.
