complex expression not allowed in dependent template argument expression

Hi,

trying to compile current Boost, I get $subject in a line that reads

(cf. http://engineering.meta-comm.com/boost-regression/CVS-HEAD/developer/output/mmu tz-bin-boost-libs-concept_check-where-test-sunpro-debug.html)

--begin excerpt--

// Here we implement the metafunction that detects whether a

// constraints metafunction exists

typedef char yes;

typedef char (&no)[2];

template <class Model, void (Model::*)()>

struct wrap_constraints {};

template <class Model>

inline yes has_constraints_(Model*, wrap_constraints<Model,&Model::constraints

>* = 0); // ### error here

inline no has_constraints_(...);

--end--

(this code is used to check for the existence of a constraints() member function in the template argument)

Neither Google nor any of the Forums here turn up anything when searching for the error message. Since the Boost regression tests indicate that this line isn't a problem for various MSVC/gcc compilers, might this be a SunPro bug? If so, is there a workaround?

Thanks,

Marc
