The assertion in load_impl suggests the author was aware these conditions are normal since the assertion evaluates to true. However, the parameters for the call to std::memcpy cannot be evaluated because an assertion within buffer_ fails. Changing load_impl to look like this fixes the problem: void load_impl(void * p, int l) { assert(position+l<=static_cast(buffer_.size())); if (l) { std::memcpy(p,&buffer_[position],l); position += l; } } It looks like the bug should also exist in Boost's trunk, but I cannot get the software I'm working on to build with Boost 1.44 and newer, but that is another issue."
