hi,
I'm having test 29 crashing on latest Arnaldo's perf/core:

[jolsa@krava perf]$ ./perf test hist
15: Test matching and linking multiple hists : Ok
25: Test filtering hist entries : Ok
28: Test output sorting of hist entries : Ok
29: Test cumulation of child hist entries : FAILED!

I was hunting this, because I though it was caused by one
of my local changes, but then realized it's public bug ;-)

but can't find the reason so far..

Huh?

[acme@jouet linux]$ perf test 29
29: Test cumulation of child hist entries : Ok
[acme@jouet linux]$ perf --version
perf version 4.7.rc5.g1c1e35c
[acme@jouet linux]$


If this helps break the tie:

dsa@kenny:~/kernel.git$ /tmp/perf/perf test 29
29: Test cumulation of child hist entries : Ok

dsa@kenny:~/kernel.git$ /tmp/perf/perf --version
perf version 4.7.rc5.g02184c

But running on net-next kernel from a few days ago + 1 local patch:
dsa@kenny:~/kernel.git$ uname -r
4.7.0-rc2-00862-g23854048c919

(I do get a few other failures)
