[PATCH 0/2] perf stat: fix segfault when closing events

[Mark Rutland]

Hi,

These patches fix a segfault seen in some cases when perf stat is exiting.

We don't balance opening/closing of events in all cases, and go out-of-bounds
when we close events. Full details in the patch 2 commit message.

Thanks,
Mark.
