--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
Right, conversion from an integer other than 0 or 1 to bool is a narrowing
conversion, narrowing conversions are not permitted in converted constant
expressions, and a non-type template argument must be a converted constant
expression.

So you get a substitution failure in the template specialization.
