<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">It seems the crash occurs at Delete for both "regular" pointers and vtkSmartPointer ?!<br>
<br>
Can someone reproduce the problem ? If yes, does somebody know what and where is the problem ?!
<br>
<br>
There are 4 situations :<br>
<br>
1. pointer commented + smart pointer allocated but not used : no crash<br>

<div>Hi,<br>
<br>
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.<br>
<br>
Regards,<br>
Andy<br>

<br>
I try to understand if (and how) I can use Catalyst for my need (in-situ visualisation). I started with :
<a href="http://paraview.org/Wiki/ParaView/Catalyst/Overview" target="_blank">http://paraview.org/Wiki/ParaView/Catalyst/Overview</a><br>
<br>
To code the adaptor, you need to handle VTK objects. When using VTK, I generally prefer to use smart pointers (avoid looking for leaks).<br>
Here is my code (this is the only call / use of VTK object in the all code)<br>
paraviewAdaptor::paraviewAdaptor ()<br>
{<br>
_spProcessor = vtkSmartPointer<vtkCPProcessor>::New ();<br>
// _spProcessor -> Initialize (); // Crash if uncommented ?!<br>
}<br>
Compilation is OK, but at run time I get a crash with this error message :<br>
*** The MPI_Comm_free() function was called after MPI_FINALIZE was invoked.<br>
*** This is disallowed by the MPI standard.<br>
<br>
So I tried to use pointers instead of smartpointers :<br>
paraviewAdaptor::paraviewAdaptor ()<br>
{<br>
_pProcessor = vtkCPProcessor::New ();<br>
_pProcessor -> Initialize (); // Don't crash ?!<br>
}<br>
And I don't get any crash anymore ?!....<br>
<br>
Why is that ? How can I use vtkSmartPointers ?<br>
<br>
Note : I use ParaView-v4.0.1-source.tgz and I run on Ubuntu 12.04<br>
<br>
Thanks,<br>
<br>
