Public bug reported: On kernels 3.13-18 and 3.13-23 (there may be others) the kernel is killing gccgo compiled binaries
[18519.444748] jujud[19277]: bad frame in setup_rt_frame: 0000000000000000 nip 0000000000000000 lr 0000000000000000 [18519.673632] init: juju-agent-ubuntu-local main process (19220) killed by SEGV signal [18519.673651] init: juju-agent-ubuntu-local main process ended, respawning In powerpc/kernel/signal_64.c: sys_rt_sigreturn is jumping to the badframe: label and executing an unconditional force_sigsegv which is delivered to the userland process. Like C++, gccgo tries to decode SIGSEGV as a nil pointer access and blame some random function that happened to be the top stack frame. Reverting to the 3.13-08 kernel appears to resolve the issue which (weakly) points the finger at the recent switch to 64k pages. ** Affects: linux (Ubuntu) Importance: Undecided Status: Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1304754 Title: gccgo compiled binaries are killed by SEGV on 64k ppc64el kernels To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1304754/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
