It is enabled with a -fsanitize flag. iotests are currently disabled when any -fsanitize option is used. Since SafeStack is useful on production environments, and its implementation may break the binary, filter it out when the check is performed, so that if SafeStack was the only -fsanitize option, iotests are still performed.
