I am getting warnings clang: warning: argument unused during compilation: '-faddress-sanitizer' when building with $ clang --version clang version 2.9 (tags/RELEASE_29/final) Target: i386-redhat-linux-gnu Thread model: posix I just assumed that my clang version was too old to know this switch. Since only the -clang-debug target was affected, I didn't care. I would prefer -clang-debug just using the option name that is required for the newest clang version(s), instead of having to adjust one more config variable. But when I change the option name in Makefile, I get clang: warning: argument unused during compilation: '-fsanitize=address' instead, for 2.9 and for 3.1. This is bad. May be HAVE_CLANG_3_2 is a good enough solution right now? How widespread is clang 3.2? Fedora 18 still uses 3.1. Frank
