I asked for help on the Fedora devel mailing list and got this, HTH! On 02/03/2016 05:59 PM, Richard Shaw wrote:

I'm not sure if this is valid C++. Warning about it is certainly appropriate. You should remove the data member, use sizeof(xml_memory_page) instead of offsetof(xml_memory_page, data), and replace page->data with reinterpret_cast<char *>(page) + sizeof (impl::xml_memory_page), or ideally, have xml_memory_page::construct() return both pointers. You probably should check for wraparound in the size computations as well, to avoid allocating less memory than requested. --- end --- Thanks, Richard
