Summary

0002841: memory leak in vtkHyperStreamline

Description

Hi all,

I have found a memory leak in vtkHyperStreamline. The internal object
this->Streamers is allocated via new each time Execute is called, however it is
only deleted when the object itself is deleted. So if the vtkHyperStreamline
object executes multiple times there is a leak, and also keeping even one copy
of the Streamers around is very very memory intensive for some reason.

The attached script demonstrates the problem (you need to run top or similar at
the same time and see how much memory is used). There are some lines in the
script that you can uncomment to demonstrate the leak. I found that adding these
lines to the end of the function vtkHyperStreamline::Execute() will fix the
problem (must be after the call to BuildTube):

delete [] this->Streamers;
this->Streamers = 0;

Thanks for looking into this!
