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.
