This function calls "va_end(args);" in two places. It also passes "args" to some callees. I think all uses of "args" need to become uses of "argsCopy", no?

Oops, "va_end(args)" is definitely wrong, but AFAIK the other uses of "args" is correct.

We should stop using String::format.

And instead use something that is type safe. Like use makeString.
