The upstream bug which was fixed and assumed to be the same bug as this one is probably not actually this bug and the guess went wrong due to lack of additional information around the pure stack trace.It can even be that this is not a CUPS bug but a bug in Avahi or D-Bus. The crash happens in D-Bus code which is called by Avahi code and this by CUPS code.
Bug 1061457 and bug 1051799 seem to be the same. Steve, can you give any info about the situations when the crash occurs for you? Like on each job, on each CUPS startup/shutdown, .. Does it only occur for a certain printer (connection type), jobs from a certain app, ...? Can you supply an error_log in debug mode (https://wiki.ubuntu.com/DebuggingPrintingProblems#CUPS_error_log) and /var/log/syslog to see what happened right before the crash. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1034045 Title: cupsd assert failure: *** glibc detected *** /usr/sbin/cupsd: free(): corrupted unsorted chunks: 0x00007f3dc478c0f0 *** Status in “cups” package in Ubuntu: Triaged Bug description: The cups job auto-restarted as intended after this crash, but this looks like a worrisome failure mode ProblemType: Crash DistroRelease: Ubuntu 12.10 Package: cups 1.6.1-0ubuntu1 ProcVersionSignature: Ubuntu 3.5.0-8.8-generic 3.5.0 Uname: Linux 3.5.0-8-generic x86_64 ApportVersion: 2.4-0ubuntu6 Architecture: amd64 AssertionMessage: *** glibc detected *** /usr/sbin/cupsd: free(): corrupted unsorted chunks: 0x00007f3dc478c0f0 *** Date: Tue Aug 7 08:03:04 2012 ExecutablePath: /usr/sbin/cupsd InstallationMedia: Ubuntu 10.04.1 LTS "Lucid Lynx" - Release amd64 (20100816.1) Lpstat: device for davidson-printer: smb://WORKGROUP/EXCALIBUR/Printer2 device for HP-Color-LaserJet-CM1312-MFP: hp:/usb/HP_Color_LaserJet_CM1312_MFP?serial=00CNB882VG58 device for HP-PSC-750: ipp://207.224.24.210:631/printers/PSC_750 device for HP-PSC-750-legal: ipp://207.224.24.210:631/printers/PSC_750 device for PSC-750: hp:/usb/PSC_750?serial=MY2ASD4157WB MachineType: LENOVO 3249CTO Papersize: letter PpdFiles: HP-PSC-750: HP PSC 750, hpcups 3.12.6 HP-PSC-750-legal: HP PSC 750, hpcups 3.12.4 HP-Color-LaserJet-CM1312-MFP: HP Color LaserJet CM1312 MFP Series Postscript (recommended) PSC-750: HP PSC 750, hpcups 3.12.6 davidson-printer: HP Color LaserJet CP3505 Postscript (recommended) ProcAttrCurrent: /usr/sbin/cupsd (enforce) ProcCmdline: /usr/sbin/cupsd -F ProcEnviron: PATH=(custom, no user) TERM=linux ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-3.5.0-8-generic root=/dev/mapper/hostname-root ro quiet splash vt.handoff=7 Signal: 6 SourcePackage: cups StacktraceTop: __libc_message (do_abort=2, fmt=0x7f3dc15f50f0 "*** glibc detected *** %s: %s: 0x%s ***\n") at ../sysdeps/unix/sysv/linux/libc_fatal.c:201 malloc_printerr (action=3, str=0x7f3dc15f5270 "free(): corrupted unsorted chunks", ptr=<optimized out>) at malloc.c:5007 ??
