 I have recently noticed an issue with the Boost Math library:
  "../boost/math/special_functions/jacobi_elliptic.hpp", line 141.46:
 1540-1187 (S) "template <class T> boost::math::jacobi_elliptic(T, T, T *,
 T *)" must not have default arguments.
  "../boost/math/special_functions/math_fwd.hpp", line 721.42: 1540-0424
 (I) "jacobi_elliptic" is declared on line 721 of
 "../boost/math/special_functions/math_fwd.hpp".

 As far as I understand from C++03 subclause 8.3.6 [dcl.fct.default]
 paragraph 4:

         For non-template functions, default arguments can be added in
 later declarations of a function in the same scope.

 the code present (preprocessed and grep'd below):

 #line 35 "../boost/math/special_functions/math_fwd.hpp"
    typename tools::promote_args<T>::type jacobi_elliptic(T k, T theta, T*
 pcn, T* pdn, const Policy&);
    typename tools::promote_args<T>::type jacobi_elliptic(T k, T theta, T*
 pcn, T* pdn);
 #line 12 "../boost/math/special_functions/jacobi_elliptic.hpp"
 inline typename tools::promote_args<T>::type jacobi_elliptic(T k, T theta,
 T* pcn, T* pdn, const Policy&)
    static const char* function = "boost::math::jacobi_elliptic<%1%>(%1%)";
 inline typename tools::promote_args<T>::type jacobi_elliptic(T k, T theta,
 T* pcn = 0, T* pdn = 0)

 does not appear to met the requirement of being a non-template function,
 and indeed has default arguments in a later declaration.
