Comment (by ngwood):

 Replying to [comment:1 ryandesign]:
 > Maybe a required header isn't being included? `std::isnan` is defined in
 <cmath>. If `#include <cmath>` doesn't appear in the affected source file,
 try adding that.
 Directly including cmath in the offending file did not resolve the issue.
