The building crosses a tile boundary. This happens with the version from a few days ago but also with the latest and greatest that fixed the other artifacts.

This is caused by the tile clipper which may introduce duplicate points which the tessellator cannot handle properly. One could disable clipping for buildings in MapDatabase... or fix the clipper :)
