If you try to use ubsan with clang, it always fails:

$ /opt/local/bin/clang -fsanitize=undefined arst.c Undefined symbols for architecture x86_64: "___ubsan_handle_add_overflow", referenced from: _main in arst-nGlYc7.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

The fix is clang should build should use cmake instead of autotools since it's basically the preferred LLVM build system at this point.
