Description

To fix an unhandled exception: 0xC0000090: Floating-point invalid operation, have to modify src/algorithm/LineIntersector.cpp line 874 from: 

#if COMPUTE_Z
	double minZ0 = n00.z < n01.z ? n00.z : n01.z;
	double minZ1 = n10.z < n11.z ? n10.z : n11.z;
	double maxZ0 = n00.z > n01.z ? n00.z : n01.z;
	double maxZ1 = n10.z > n11.z ? n10.z : n11.z;
	double intMinZ = minZ0 > minZ1 ? minZ0 : minZ1;
	double intMaxZ = maxZ0 < maxZ1 ? maxZ0 : maxZ1;
	double intMidZ = (intMinZ + intMaxZ) / 2.0;
	normPt.z = intMidZ;
	n00.z -= normPt.z;
	n01.z -= normPt.z;
	n10.z -= normPt.z;
	n11.z -= normPt.z;
#endif

To: 

#if COMPUTE_Z
	if( !ISNAN(n00.z) )
	{
		double minZ0 = n00.z < n01.z ? n00.z : n01.z;
		double minZ1 = n10.z < n11.z ? n10.z : n11.z;
		double maxZ0 = n00.z > n01.z ? n00.z : n01.z;
		double maxZ1 = n10.z > n11.z ? n10.z : n11.z;
		double intMinZ = minZ0 > minZ1 ? minZ0 : minZ1;
		double intMaxZ = maxZ0 < maxZ1 ? maxZ0 : maxZ1;
		double intMidZ = (intMinZ + intMaxZ) / 2.0;
		normPt.z = intMidZ;
		n00.z -= normPt.z;
		n01.z -= normPt.z;
		n10.z -= normPt.z;
		n11.z -= normPt.z;	
	}
#endif
