@mmoroz -- Could you please look into the issue, kindly re-assign if this is not related to your changes.
Thank You.

Hm, it's hard for me to say whether this is a bug or not. This testcase exceeds timeout of 25 secs on Debug build. On Release build it takes ~16-17 seconds to be processed, which probably can be fine according to its size of 390KB.

John, what do you think about that?
