Package: libc6 Version: 2.13-35 Severity: serious Tags: upstream patch Hi folks,
Just been directed to the bug discussion at http://sourceware.org/bugzilla/show_bug.cgi?id=13844 In some cases, the (e)glibc build will pick up an incorrect version of lowlevellock.c and this can cause futex deadlocks. Although the subject specifically mentions sparc, this is expected to impact ARM too. AFAICS our current eglibc in unstable will include this problem.
