This crash seems like it is occurring trying to access vertex_shader->set_uniform_matrix4fv. The crash address of 0x10 hints that vertex_shader is NULL, which would occur if for some reason we didn't set the shader. This would most likely occur because linking it failed - a bad shader name was supplied or something of that sort.
