Christian,

I'm not sure myself, but quick look suggests me there are some related
or different problems too:

In gil/extension/io_new/formats/tiff/is_allowed.hpp,
missing template keyword around line 65

p->template read_data< row_buffer_helper_view< View > >( plane, K );

and missing qualifier around line 800 in:

            parent_t::init_image( images
                       , this->_info
                       );

In gil/extension/io_new/formats/tiff/is_allowed.hpp, around line 126

compare_channel_sizes_fn fn( &channel_sizes.front() );

does not seem to match any ctor of compare_channel_sizes_fn.

There is also mismatch of unsigned short* vs unsigned int*.

I will try to continue checking tomorrow.
