[Paraview] RE : Catalyst : crash using vtkSmartPointers

Mon Aug 5 08:46:17 EDT 2013

It seems the crash occurs at Delete for both "regular" pointers and vtkSmartPointer ?!

Can someone reproduce the problem ? If yes, does somebody know what and where is the problem ?!

There are 4 situations :

1. pointer commented + smart pointer allocated but not used : no crash

...

{
  _spProcessor = vtkSmartPointer<vtkCPProcessor>::New();
//  if ( _spProcessor ) _spProcessor -> Initialize ();
//  _pProcessor = vtkCPProcessor::New();
//  if ( _pProcessor ) _pProcessor -> Initialize ();
  cout << "adaptor OK" << endl;
}
adaptor::~adaptor ()
{
//  if ( _pProcessor ) _pProcessor -> Delete ();

I don't understand why this is crashing !?...

Objet : Re: [Paraview] Catalyst : crash using vtkSmartPointers

Hi,

I didn't have any problems using a vtkSmartPointer for vtkCPProcessor. I'd have to see your full code to know for sure but my guess is that _spProcessor is a pointer to a vtkCPProcessor and not a vtkSmartPointer<vtkCPProcessor>. When I make that mistake I get a crash.

Regards,
Andy

Hello,

I try to understand if (and how) I can use Catalyst for my need (in-situ visualisation). I started with : http://paraview.org/Wiki/ParaView/Catalyst/Overview

To code the adaptor, you need to handle VTK objects. When using VTK, I generally prefer to use smart pointers (avoid looking for leaks).
Here is my code (this is the only call / use of VTK object in the all code)
paraviewAdaptor::paraviewAdaptor ()
{
  _spProcessor = vtkSmartPointer<vtkCPProcessor>::New ();
//  _spProcessor -> Initialize (); // Crash if uncommented ?!
}
Compilation is OK, but at run time I get a crash with this error message :
*** The MPI_Comm_free() function was called after MPI_FINALIZE was invoked.
*** This is disallowed by the MPI standard.

So I tried to use pointers instead of smartpointers :
paraviewAdaptor::paraviewAdaptor ()
{
  _pProcessor = vtkCPProcessor::New ();
  _pProcessor -> Initialize (); // Don't crash ?!
}
And I don't get any crash anymore ?!....

Why is that ? How can I use vtkSmartPointers ?

Note : I use ParaView-v4.0.1-source.tgz and I run on Ubuntu 12.04

Thanks,

FH
