I wish I could have understood this issue. I tested a variety of
things, examined my executable with ldd, tried various cmake variable
changes. The problem persisted until I got rid of the ParaView 3.6.2
distribution, downloaded it again, and built again. That fixed the
problem. So I figured I would post this to the list in case any other
unfortunate developer has the same problem.

Can you verify that the xml for your plugin is valid? Just open in up
in firefox or something to make sure that the xml syntax is correct.

I am working with a file-reading filter. There are no error messages or
warnings when I compile. After I build, I copy the filter .so files to the
bin/plugins location, where they are automatically detected by paraview.
When I choose the File, all goes well. The usual RequestDataObject and
RequestInformation methods are executed. All my debug output looks fine.
When I press the Apply button, I know that RequestData is messaged and it
seems to finish its work OK.
As an aside, my vtkDebugMacro output now only shows up in the gdb terminal
output; it stops going to the output messages window of Paraview. I don't
know what that means, except that it seems to tell me that something is
going haywire near the start of RequestData, even though that method seems
to run fine. (I suppose I'm not seeing it in the output messages window
because that window may be buffered?)
The actual crash seems to happen just about when ParaView would normally be
drawing an empty cube outline on the screen (the reader puts a rectilinear
grid into the pipeline).
In the traceback (below), it looks like ParaView is messaging vtkSMProxy
object that has not been instantiated... this=0x0
Has anyone seen this before? Any suggestions on how to debug further?
Thanks,
Erik
