Can you confirm if it's that specific patch which made it worse? Or a range of releases?

[m15o]

I can confirm that until version 37.387.0 or below, memory usage is normal. (average 2gb memory usage in 4gb system)
And version 37.387.2 or avobe, I got out of memory error (even at at 6gb system.)

I dont have version 37.387.1 result. I suspect 37.387.2 because of the re2 issue.
