Karma real generators output "inf" when attribute is integral 0

Reported by: K-ballo <kaballo86@…> Owned by: Joel de Guzman
Milestone: To Be Determined Component: spirit
Version: Boost 1.52.0 Severity: Problem
Keywords: Cc:

Description

Karma real generators output "inf" instead of the expected "0.0" when the supplied attribute is an integral 0. This is because the implementation of is_infinite compares the attribute to std::numeric_limits<T>::infinity() without checking std::numeric_limits<T>::has_infinity.
