PVS-Studio warning V639 for Eigen

template<typename Scalar> EIGEN_DEVICE_FUNC
inline bool isApprox(const Scalar& x, const Scalar& y,
  typename NumTraits<Scalar>::Real precision =
    NumTraits<Scalar>::dummy_precision())

template< .... >
void evalSolverSugarFunction(....)

This suspicious code was found in Eigen project by PVS-Studio static code analyzer.
Warning message is:
V639 Consider inspecting the expression for 'isApprox' function call. It is possible that one of the closing ')' brackets was positioned incorrectly. polynomialsolver.cpp 123
