<br>
Crashes that only occur in parallel can be hard to debug. The
memory inspector makes it easy to attach gdb to any of ParaView's
processes. After you've connected to the parallel pvserver, open
the memory inspector, right click on the process of interest,
select remote command. If your local then use local gdb template.
There's a remote gdb template to support remote debugging where
the remote system provides ssh access to compute nodes. It works
for most clusters, I've never been able to make it work the Cray.
A second option is to pass --enable-bt on the command line when
you start pvserver. Again on Cray it's problematic, but Cray
provides it's own solution called ATP. You just link against it
and set their special environment variable when you submit your
job. All of these options require a Debug or RelWithDebInfo build.

Hope this helps!<br>

<p class="MsoNormal">I have a custom filter that takes two input
