[Paraview] BUG in vtkPVDataSetAttributesInformation on Linux ?

[R M]

Hi,

I use paraview 3.9.0 on a Centos 5 32 bits and also Windows XP.

Here' my problem. I have developed a plugin with temporal data and with windows 
XP it works. But under linux I have a crash of paraview during some time step 
change.
In Debug I have the following error message:

///////////////

  const vtkPVDataSetAttributesInformationSortArray & thatArray )
{
  
#if defined(_WIN32)
  return  (  stricmp( thisArray.arrayName, thatArray.arrayName )  <=  0  )
          ?  true  :  false;
#else
  return  (  strcasecmp( thisArray.arrayName, thatArray.arrayName )  <=  0  )
          ?  true  :  false;
#endif
}

In linux it use:  (  strcasecmp( thisArray.arrayName, thatArray.arrayName )  <=  
0  ) an d when it crashed, the size of thisArray.arrayName.arrayName is 0 (and 
thatArrayName.arrayName is OK).

So what can it be bone to avoid this crash with Linux ?
