[Bug 1965112] Re: cupsd crashed with SIGSEGV in __strcmp_evex()
Thanks for all the info, it is as I expected, your cupsd.conf has "Browsing No" because you do not use printer sharing. Then the DNS-SD host name is not set in the daemon's internal variable DNSSDHostName and this variable I compared with the host name of the URI of the potential new queue to see whether I have to change it to "localhost" for the case that the printer is a local service (IPP-over-USB, Printer Application, ...). This caused the crash. Now I have added a fallback to the internal variable ServerName if DNSSDHostName is NULL. I could reproduce the bug by doing the command cupsctl --no-share-printers (I had printer sharing on for my OpenPrinting work) and re-trying to access an IPP printer through GTK's print dialog which caused the crash then for me. I have the fix now ready and with it the crash goes away. I will update the Pull Request on CUPS upstream (https://github.com/OpenPrinting/cups/pull/353) and also the patch on the Ubuntu package.

Can you also attach your /etc/cups/cupsd.conf file?

Could you run the following commands: driverless driverless --std-ipp-uris lpstat -v and post the output here. On which print queue are you printing? Are you running cups-browsed? Then switch CUPS into debug mode: cupsctl --debug-logging Print a job as you did when the crash happened. When it fails again, take the /var/log/cups/error_log file and attach it to this bug report. DO NOT compress or package it. Could you also tell me how you printed the job? Which application? GTK print dialog? Any other print dialog? ** Changed in: cups (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1965112 Title: cupsd crashed with SIGSEGV in __strcmp_evex() To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1965112/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
