Package: cups Version: 1.4.4-7+squeeze1 Severity: important cupsd seems to crash with SIGSEGV on me every day, seems related to some job it doesn't like, as the crash time corresponds to the start of an ipp process for that job. Does this look like a known issue (possibly fixed in sid)?

The dbus code has changed quite a lot since Squeeze and there are still crashes (and fixes for them) being fixed; 1.7.1-6 that I just uploaded has two of such fixes. I'm therefore marking this bug as fixed in the current version in unstable, although I think this bug is most probably still present in Squeeze. > BTW having to patch cups in order to debug it seems silly, I had to > - add --enable-debug to the configure flags to prevent stripping > making the cups-dbg package completely useless This has been applied in 1.5.0-6 and is therefore in wheezy+. > - apply this change to get a core dump: > > --- cups-1.4.4.orig/scheduler/main.c > +++ cups-1.4.4/scheduler/main.c > @@ -414,14 +414,6 @@ > > #ifndef DEBUG > /* > - * Disable core dumps... > - */ > - > - getrlimit(RLIMIT_CORE, &limit); > - limit.rlim_cur = 0; > - setrlimit(RLIMIT_CORE, &limit); > - > - /* > * Disconnect from the controlling terminal... > */ Well, this would become enabled given --enable-printfs, which has a wider impact. I don't currently intend to patch this. Cheers, OdyXAttachment: signature.asc
