http://bugzilla.suse.com/show_bug.cgi?id=1047882 Bug ID: 1047882 Summary: glibc deadlock in __lll_lock_wait_private Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem Assignee: bnc-team-screening@forge.provo.novell.com Reporter: martin.liska@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hello. Recently I see various deadlock on my system when running a periodic GCC stress tester. Back trace is as follows: Try: zypper install -C "debuginfo(build-id)=a0ea882cb1b7b503cb00da1c4699334c139f8817" (no debugging symbols found)...done. __lll_lock_wait_private () at

reproducer, the problem happens once in couple of hours. Any ideas how to debug that? I can provide more info if desired. -- You are receiving this mail because: You are on the CC list for the bug.
