OK, thanks for the info. I think we can safely say that Windows doesn't (and probably can't due to microarchitectural limitations) support more 47 bits. How about, in addition to the comment about evading the OOM killer, we add `if (i < 48) ok(GetLastError() == 0xdeadbeef || GetLastError() == ERROR_NOT_ENOUGH_MEMORY, ...) else ok(GetLastError() == ERROR_INVALID_PARAMETER, ...)`?
