Problems on Ubuntu-GCC_master_CXX20-Release

[afabri]

Issue Details

As the platform uses the latest version of the compiler ( c++ (GCC) 12.0.1 20220206 (experimental) it is no surprise that there are more warnings and errors. It uses -std=c++2a and we use the latest version of boost.

In Point Set Processing Examples it does not find boost date time.

In Polygon Mesh Processing we have a timeout (6000 sec) so it probably loops somewhere as we are in -O3.

In Surface Mesh Deformation we have an error concerning Eigen

error: no matching function for call to 'Eigen::JacobiSVD<Eigen::Matrix<double, 3, 3> >::compute(const CGAL::Deformation_Eigen_closest_rotation_traits_3::Matrix&, int)'

In Polynomial we get a warning that sounds serious, In case it is a false alert we better hide it:

/mnt/testsuite/include/CGAL/Handle_with_policy.h:190:39: warning: pointer used after 'void operator delete(void*, std::size_t)' [-Wuse-after-free]
