Excellent, thanks! Can you either: (a) send me a tarball of your altqd binary together with all the shared libraries and .debug files that gdb mentioned, and together with a core dump of the process (you should be able to get one by sending it SIGABRT); or (b) print the the contents of the ifinfo->cllist queue? For (b), you will need to do: (gdb) print *ifinfo (gdb) print ifinfo->cllist->lh_first (gdb) print *ifinfo->cllist->lh_first (gdb) print ifinfo->cllist->lh_first->next.le_next (gdb) print *ifinfo->cllist->lh_first->next.le_next (gdb) print ifinfo->cllist->lh_first->next.le_next->next.le_next (gdb) print *ifinfo->cllist->lh_first->next.le_next->next.le_next ... and so on, until the next.le_next member is null, or until you get bored of printing the next element which might indicate a cycle. (Not sure how many classes in this list to expect, probably depends on your altq configuration.)
