Do you mean, does asan compilation cause some special preprocessor symbol to be defined? No, asan compilation does not define any preprocessor symbol. In clang, there are two ways to workaround asan-hostile code: one is a function attribute and another is __has_feature macro http://clang.llvm.org/docs/AddressSanitizer.html#has_feature Both are clang-specific today, but both make sense in gcc as well. --kcc
