Hi,

I want to use scoped_ptr with std::vector or scoped_array, but the  
problem is that the type I want to allocate has a non-trivial  
constructor.

What is the standard way to make this work? My current best guess is  
to use std::vector with boost::scoped_ptr in the following way:

TextureUnitsController::TextureUnitsController ()
{
        GLint textureUnitCount = 1;
        glGetIntegerv(GL_MAX_TEXTURE_UNITS, &textureUnitCount);

        m_textureUnits.resize(textureUnitCount);
        
        for (unsigned i = 0; i < textureUnitCount; i += 1) {
                m_textureUnits[i].reset(new TextureUnit(GL_TEXTURE0 + i));
        }
        
        std::cerr << "Found " << textureUnitCount << " texture units..." <<  
std::endl;
}

But this doesn't work because scoped_ptr also has a non-trivial  
constructor, so resize fails.

Thanks
Samuel
