Core dumps "often"

Development
1

Not sure how to report this bug(s)… but I get core dumps now and then. I just got one by dragging my mouse in the rendered view of my data. I had started Paraview with the terminal. This is what I see:

Please provide:

  • ParaView version and how it was installed
  • Help → About content
  • Exact steps to reproduce the issue

Best,

I would not be able to reproduce it 100% of the time. I just load my data, “play around” with calculators, lines, dragging my mouse over the rendered section, and I would get crashes now and then. So I haven’t yet pinpointed these crashes to a single culprit.

Edit: Let me know if there is a log file that could help.

Please use the binary release from https://www.paraview.org/download/

Is it for some specific reason? Or just that it’s version 6.2? In which case I’ll just wait until this version hits Arch Linux repository.

The ArchLinux version is maintained by ArchLinux maintainers, the binary release version is maintained by Kitware.

I’m not suggesting the cause of the bugs you see to be specifically the ArchLinux package, just that you won’t get support for it here and I wont be able to help.

If you reproduce the issues using the binary release, then we can help.

Usually I would try myself with the binary release but you do not provide specific steps to test.

In conclusion, ParaView is not supposed to core dump “often” (or at all) so please try with the binary release and let us know if that fixes it. I cant help with anything regarding specifically the ArchLinux package.

I see, thanks a lot for the information. I’ll be using the official Paraview binary and report here if I get another core dump.
