I made terminal dump of the gdb session using script command so by "cat python_testing_jupyter-server_pytest.log" on current termilnal you may see full gdb back trace with original colouring.

Please let me know what I can do more to diagnose that issue or if you need more details.

I can add that exactly that python binary was up to now rock solid on building, minstalling and testing +800 python modules as rpm packages.
