canon-cups-ufr2 5.70 prints blank pages for Canon MF743CDW

[dmayle]

Describe the bug

When trying to print using the canon-cups-ufr2 print driver version 5.70, no pages are output, and the printer job log (printer web UI, not CUPS) shows the job succeeding, but with zero pages. I believe it's due to a segfault in cnrsdrvufr2, the binary which converts to the ufr2 language the printer understands

Steps To Reproduce

Steps to reproduce the behavior:

1. Install canon-cups-ufr2
2. Add network printer to CUPS, using the manufacturer Canon, and model MF743CDW UFR II
3. Try to print anything

Expected behavior

Print output

Screenshots

N/A

Additional context

As a workaround, I enabled IPP and Mopria on the printer web interface, and added the printer to CUPS at the url ipp://<my_printer_address>/ipp/print and selected the driver Canon->IPP Everywhere, which allows me to print with less functionality (the two-sided printing doesn't seem to be supported).

I also tried updating the driver to 5.90, but that version has the same problem.

I've tried setting enable dontStrip and separateDebugInfo, but the package uses a builtin set of scripts to compile, and these values seem to have no effect.

As such, when I try to use gdb, I have no useful symbols and can't figure out what's going wrong. strace hasn't been helpful either...
