.NET CoreCLR
V698 Expression 'memcmp(....) == -1' is incorrect. This function can return not only the value '-1', but any negative value. Consider using 'memcmp(....) < 0' instead. sos util.cpp 142
bool operator( )(const GUID& _Key1, const GUID& _Key2) const
{ return memcmp(&_Key1, &_Key2, sizeof(GUID)) == -1; }
In cases like this, you should check one of the three states: '< 0', '0', or '> 0'.
