SUMMARY: UndefinedBehaviorSanitizer: function-type-mismatch /test/10.6_dbg_san/mysys/mf_keycache.c:6152:5

Observed using UBSAN with Clang and LLMV 18.1.3:
sudo apt install clang llvm-18 llvm-18-linker-tools llvm-18-runtime llvm-18-tools llvm-18-dev libstdc++-14-dev llvm-dev llvm-17-linker-tools # llvm-17-linker-tools installs /usr/lib/llvm-17/lib/LLVMgold.so, which is needed for compilation, and LLVMgold.so is no longer included in LLVM 18 |
sudo ln -s /usr/lib/llvm-17/lib/LLVMgold.so /usr/lib/llvm-18/lib/LLVMgold.so |
