#define CRY_GCC48_AVOID_OPTIMIZE

Workaround for bug in GCC 4.8. The kind of access patterns here leads to an internal compiler error in GCC 4.8 when optimizing with debug symbols. Two possible solutions are available, compile in Profile mode without debug symbols or remove optimizations in the code where the bug occurs see http://gcc.gnu.org/bugzilla/show_bug.cgi?id=59776
