No, because this is GCC switch and I'm using both Visual Studio 2015 Compiler and Clang. I will try to build it with GCC (on Windows) in next couple of...

Yes, I think so (my SVN path is https://github.com/mapbox/wagyu.git/trunk). This is piece of code that I've posted in the first comment.

Confirming. This one is resolved. But same assert triggered in the other place: ``` template void next_edge_in_bound(active_bound_list_itr& bnd, scanbeam_list& scanbeam) { ++((*bnd)->current_edge); ++((*bnd)->next_edge); ``` mapbox\geometry\wagyu\active_bound_list.hpp, line 165 (*bnd)->next_edge is NULL...

Are you really sure about clang? The makefile you've posted above is for GCC because compiler options there are in GCC format. For example, clang doesn't understand -std=c++11, it says...

Looks like it's an STL assert in Microsoft's STL implementation. In Release configuration it works, producing no asserts. So if you not supporting Microsoft Visual Studio, you can close the...

Sounds good! Maybe I could fix some of these asserts while you don't have Microsoft environment. When I have time. What is the best way to contribute? Branch? Patch?
