IPP crashes after every successfully completed job since 2.4.2

[Nils-TUD]

Since I upgraded to CUPS 2.4.2, the IPP backend crashes every time after the print is complete. Therefore, I need to manually cancel the job and resume the printer afterwards. I just downgraded to 2.4.1 again and there it still works.

That's the output from coredumpctl gdb:

Sorry, I just noticed that I reported this issue in the wrong repo. I reported it again here. Since the git history and version numbers look pretty different, I assume that the issue does not exist in this repo.
