Thanks for filing this bug report. How reproducible is this issue? Looking at the backtrace in attachment 593963 [details] I see that the SIGBUS occurred whilst Python's garbage-collector was running update_refs is called at the beginning of collecting a particular generation (in this case the middle-aged objects), and walks a linked-list of all reference-owning objects doing some initial setup for the collection. So perhaps the linked list has become corrupt, or perhaps one of these objects has been prematurely deallocated?
Its only happend once. I think that it crashed while abrt was running (for an other bug report). I figured out today that I had way more bugs with kernel 3.4.3 than with 3.4.2 one. I dont know what can I do to help. :s
Thanks for the information. Given that the bug has only been seen once, I don't think it's possible to investigate this one further: I believe that we're seeing a stray pointer corruption in one of the libraries linked into the process (see attachment 593964 [details]), as per comment #4, but there's no way to tell where, unless we see the bug again. I'm going to close this one out with resolution "INSUFFICIENT_DATA"; feel free to reopen if you see it again. Sorry not to be more useful.
Is it possible that this is the same bug ? https://bugzilla.redhat.com/show_bug.cgi?id=799528
(In reply to comment #7) > Is it possible that this is the same bug ? > > https://bugzilla.redhat.com/show_bug.cgi?id=799528 Perhaps, but there are differences: bug 834827 happens inside Python's garbage collector, whereas bug 799528 happens inside glibc's implementation of the heap, a layer of abstraction lower.
