Here in Sweden I can't recall such discussions. Large casualties from battles in Leningrad and Berlin involved millions of civilian deaths, but it mostly the actions made afterward when citizens surrender that get classified as a war crime and not the battle itself. Even explicit bombing of citizens, like The Blitz, are usually not refereed as a war crime even if it should fit the definition.

However, when discussing wars occurring in modern time, aerial and artillery bombardment that hit civilian targets do get refereed as war crime. Anti-personnel mines has also been added, which is seen as a war crime by most countries except for those who continue to use them.
