About JSON output generated by "bench-malloc-thread"

[Francesco <francesco dot montorsi at gmail dot com>]

Hi,
I was curious to run some benchmarks for different allocators and I found
out the benchtests/bench-malloc-thread utility.
However apparently it's producing a JSON output that is not following the
"benchout.schema.json" schema presnt under benchtests/scripts. Is this a
known/desired behavior?
(this is on latest git master branch)

How am I supposed to graph the results of that benchmark utility?

This is what I get calling "compare_bench.py":
