Hello,

I have found another error in ParaView 5.8.0-RC1 in the ParallelDIY2 Filter file vtkGenerateGlobalIds.cxx when compiled with gcc 4.8.5 on RHEL 7.7.

Here is the error

~~Seems like we should add a ctor for `nullptr_t` to `vtkSmartPointer`? @robert.maynard @chuckatkins Thoughts?~~

Nevermind, Cory beat me to the punch 🙂 .
