You helped us with the out GXX_EXPERIMETAL guard. testing on Apple and Clang revealed the need for the inner guard (from https://code.google.com/p/owasp-esapi-cplusplus/source/browse/trunk/esapi/util/zAllocator.h): #if defined(__GXX_EXPERIMENTAL_CXX0X__) && __GNUC__ == 4 && __GNUC_MINOR__ < 7 // Why is Apple defining __GXX_EXPERIMENTAL_CXX0X__ # if !(defined(ESAPI_OS_APPLE) || defined(ESAPI_OS_ANDROID)) template<typename U, typename...
