I'm running with your patch now and so far so good.
Unfortunately the problem isn't repeatable, but it usually shows up within
an hour or so of fuzzing (although there's possibly a 2nd unrelated bug
that also shows up sometimes).
If you want to try running the fuzzer on your machine too just do:
git clone https://github.com/deater/perf_event_tests.git
cd fuzzer
make
and then try running the "./fast_repro98.sh" script, as that's the forking
workload I've been using when tracking this issue.
