Comment 1 for bug 1340038

The issue has been fixed in upstream version 3.10.48 (to be more specific, commit 8c6fa0a671dc12ee3dd658dafbd1d4a7fec2250d "`ptrace,x86: force IRET path after a ptrace_stop()').

Ubuntu team has released a fix for 2.6.32 (see https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1337339, http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux_2.6.32-64.127.diff.gz), but there's no official update for CentOS 6.5/RHEL 6.
Should we wait for one, or we can peek the fix from Ubuntu (which is basically equivalent to commit 8c6fa0a671dc12ee3dd658dafbd1d4a7fec2250d )?
