    Description

      Came from investigation on BF-18408. It seems like a platform/hardware specific bug. Not able to reproduce in my local machine but I was able to reproduce on Amazon EC2 instance.

      E.g., cursor id 8388079694692667449, when printing via LOGV2 (or via javascript layer print()) it displays some corrupted value, like, 8388079694692667000.

      P.S: Based on my analysis, the real data isn't corrupted, just the value that gets printed are corrupted (both in c++ and javascript layer).
