ULong64_t is a typedef from upstream intended for I/O use (i.e. a guaranteed 64b integer type). However, it was not typedef to uint64_t (the standard type) on all platforms, but to either unsigned long long (Mac, Linux) or uint64_t (Windows). As you can see from the format warnings above, that just isn't portable. Worse, some of the upstream legacy code that was still retained, would transform all occurances of unsigned long long to ULong64_t, even as there is no guarantee that the former will be 64b on all platforms.

For these reasons, ULong64_t is now gone, with the unfortunate side effect that the above test fails. Recommend to use uint64_t instead, or to reintroduce typedef unsigned long long ULong64_t in the test code (on Linux/Mac).
