Hi Amit,

Thanks for testing! That output is exactly what an unpatched summarizer produces
on my machine. I suspect the fix didn't make it into your build.
Also the test passes for me on Windows CI with the patch applied [0].

Could you double-check that you observe the failure?

Best regards, Andrey Borodin.
