[Paraview] Segfault in ParaView 4.4 RC2

[Utkarsh Ayachit]

Matthieu,

> - If I run the application from the VM's graphical interface, it runs fine. It only gives me the OpenGL warning I mentioned before. BUT the generated file has a big black area (see image_2.png attached). Also I see a window appear for a brief moment with the correct (full) view, then it disappears. I don't know why I get that.

I've seen this happen with the view size is greater the X window size.
Try changing the ViewSize to something small, say 200x200. Does that
work? If so, you'd need to change the X window size. Other option
would be build with OSMesa support. Since you're only using this build
for Catalyst, OSMesa will circumvent all the X related issues you've
been seeing on this VM.

> - If I connect to the VM through SSH with -X (otherwise I get the bad display error) and run the application, Catalyst also outputs an image, but this image also has an artifact (see image_1.png attached), and then the application crashes in a segfault, outputing a backtrace (*** glibc detected *** ./Mandelbulb: munmap_chunk(): invalid pointer: 0x00007faffb503010 ***).
> In the backtrace, the first line (so the last function call) is this:
> /home/mdorier/ParaView-build/lib/libvtkCommonCore-pv4.4.so.1(_ZN20vtkDataArrayTemplateIhE11DeleteArrayEv+0x4b)[0x7fb028c257fd]

I am going to try your code to see if i can reproduce this one. I'll
get back to you shortly.
