Description

please see https://github.com/sthielo/go-sqlite-memleak, where we stripped our code eventually terminating with an OutOfMemory exception using sqlite in-mem to produce what looks like a memory leak.

README gives some more explanations and observations, but one observation I would like to take upfront here: we only observe that problem on lilnux and not on windows.

We have no clue on the problems origin. Any help very much appreciated. Our code? Go-sqlite3 code? sqlite code?

Research direction
