6296	wrong has_trivial_constructor value for custom class follows to programm fail	azubanov@…	Gunter	"System:
 -- Windows Server 2008 R2 x64

I use wrapper for MPFR (http://www.holoborodko.com/pavel/mpfr/) and custom std::complex type implementation for mpreal class (see attachment)

typedef mpfr::mpreal					number;
typedef std::complex<number>				complex;
typedef boost::numeric::ublas::matrix<complex>		cmatrix;

cmatrix m1 = E - J;
// E, J -- cmatrix

storege.hpp:
explicit BOOST_UBLAS_INLINE
        unbounded_array (size_type size, const ALLOC &a = ALLOC()):
            alloc_(a), size_ (size) {
          if (size_) {
              data_ = alloc_.allocate (size_);
		// has_trivial_constructor returns true for complex<number>,
		// but this is my custom class with implemented default construtor
              if (! detail::has_trivial_constructor<T>::value) {
                  for (pointer d = data_; d != data_ + size_; ++d)
                      alloc_.construct(d, value_type());
              }
          }
          else
              data_ = 0;
        }"	Bugs	new	To Be Determined	uBLAS	Boost 1.48.0	Problem		has_trivial_constructor
