[Paraview] error when compiling Paraview 5.4 macOS 10.13

[Cory Quammen]

Sergio,

This problem was fixed in November 2016, so I am surprised you are
running into it. Current ParaView master includes VTK that contains
the commit

commit 33631146a85dfa64433c3997f166cbaa96bedee9

    [bugfix] Invalid pointer comparisons.

    The code was performing a null pointer check
    using (void*)Data <= 0 instead of Data == NULL
    (or nullptr). This results in a compilation
    error with clang trunk (future clang 4.0).

Make sure you have run `git submodule update` to ensure your VTK is up to date.

HTH,
