wrong has_trivial_constructor value for custom class follows to programm fail

[azubanov@…]

System:

-- Windows Server 2008 R2 x64 -- Visual Studio 2010

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;

}
