# We have a separate ASAN config for Mac OS to workaround a couple of bugs:
# 1. https://github.com/bazelbuild/bazel/issues/6932
#    _FORTIFY_SOURCE=1 is enabled by default on Mac OS, which breaks ASAN.
#    We workaround it by setting _FORTIFY_SOURCE=0 and ignoring macro redefined
#    warnings.
# 2. https://github.com/google/sanitizers/issues/1026
#    LSAN is not supported by the version of Clang that ships with Mac OS, so
#    we disable it.
