Nico,

Exactly right.  If I follow those instructions and build with configure/make then I get a clang that accepts -faddress-sanitizer.  Thanks.

But if I build with CMake, which is what I usually do, it still doesn't seem to work.  Should it?  Is there a special option to turn on?  LLVM_BUILD_RUNTIME and LLVM_INCLUDE_RUNTIME are on by default, if they're related.

Cheers,
