Focus on the line above that one:
N::value < len ? len - N::value : 0
If you add parentheses, the error goes away:
(N::value < len) ? len - N::value : 0

I'm not sure if this is a Microsoft compiler issue (I will post to them as well), but I feel like someone should add those parentheses (and then some) to the line since it is safer - the "<" can be easily confused for a template bracket instead of a less-than sign by a parser.
According to the standard, it is not parsed as a template unless you say `N::template value`. Are you using `/permissive-`? That sometimes helps with these issues. In Christ, Steven Watanabe
