Can we print fatal Qt messages despite abort()?

[The-Compiler]

As outlined in Troubleshooting — pytest-qt documentation, when Qt calls abort, often the user doesn't have any useful information due to pytest's output capturing.

I can see two ways around this, which might be worth exploring:

• Disable pytest output capturing while creating a QApplication
• Use qInstallMessageHandler to set up a custom message handler which prints some messages (fatal ones, at least) to a separate non-captured output stream (like faulthandler support in pytest)

Not sure if (especially the first one) could get too noisy though, Qt might print some unrelated stuff at startup maybe...
