[Paraview-developers] Infinite recursion during error message printout

[David Thompson]

Hi all,

I'm developing a PV-branded app and have run into an issue where my code calls vtkErrorMacro() and it recursively reprints the error message until the stack is exhausted. A partial stack trace is below (all but the bottom-most entry repeat until a crash). You can see that the vtkErrorMacro call invokes vtkOutputWindow::DisplayText, which invokes a vtkCommand::MessageEvent event. ParaView's progress handler listens for the event and then re-broadcasts the message to the vtkOutputWindow, which invokes the same event again.

There do appear to be 2 SubjectHelpers involved (0x0000000129905c90 and 0x00000001294fba80); I'm not sure if this is significant but am hoping whoever knows about the pqProgressManager will understand what's going on.

Any ideas?

	Thanks,
	David
