[3dprinter-general] Bug#925664: (no subject)

The Fedora maintainer already reported the issue upstream and applied a patch:
https://src.fedoraproject.org/rpms/CuraEngine/blob/master/f/CuraEngine-gcc9.patch

However, this patch makes the package unbuildable on GCC 8, so it will need
additional logic to work on both compilers.
