[Bug 1650493] Re: numastat <pid> fails with double free or corruption
So to summarize:
- per latest IBM comment the version in 18.10 2.0.11-2.1 works
- This is also the version in 18.04, so that works as well
- But the referred fix (pointed out in comment #13 that is actually supposed in Upstream version
2.12) is NOT in any of those package versions
I'm marking the bug tasks accordingly for 18.04/18.10 as fixed due to
that, but clearly there is some confusion going on - so I keep the main
task on incomplete to reflect that.
Either the fix mentioned was not the actual fix needed or the recent
tests were not testing the case correctly.
Given this confusion at the current state no SRUs are planned, so I'll
mark Xenial as Won't Fix to make that clear as well.

=============
Recreation Steps
=============
1. Configure host with hugepages
2. Start a guest and attach following memory device xml,
<?xml version='1.0' encoding='UTF-8'?>
<memory model="dimm"><target><size unit="KiB">8388608</size><node>0</node></target><source><pagesize unit="KiB">16384</pagesize><nodemask>0</nodemask></source></memory>
3. Set the rules in guest
4. execute numastat of guest pid
Expected Result :
Provide PID numastat
# numastat 55119
Per-node process memory usage (in MBs) for PID 55119 (qemu-system-ppc)
