I suppose it's a bug that pstack doesn't report any errors from gdb. However, that isn't in the scope of this report. -- no pstack for amd64 https://bugs.launchpad.net/bugs/532000 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
