I'm not sure if this is a bug in GCC but it doesn't seem helpful. With -Wshadow=local only local variables trigger the warnings. With it, variables and parameters to lambda function also cause warnings but this could be considered useful since it's possible for them to refer to variables outside of the lambda function.
