Subject: [PATCH 0/2] perf metricgroups: A couple of fixes

This series fixes a couple of subtle issues.

The first fixes a segfault from on my x86 broadwell when running the
'stat' command with a particular order of metrics.

As mentioned at [0], there is a pre-existing issue here which needs fixing
as this still does not work properly; however I think that is a bigger job,
and getting rid of the segfault is best I can do for the moment.

The second fixes an issue of an uninitialized variable. As noted in the
commit message, gcc does not seem to do a good job of picking up on this.
