I have the pure C++ application (attached) which uses the LDPC class in question without causing any leaks. 
The C++ code can be found on the same folder.
If you have Qt Creator, you could just open the .pro file. Otherwise, g++ will do.

My suggestion at this point is to take the -exact- "work" code from a block that seems to be causing this memory issue and move it into a test program as a subroutine. Then, from "main" create a replicated set of calls to this "work" and see what happens. The goal here is to remove the GR part of the coding, reducing the code-at-issue to its minimum to show the issue -- or, not show the issue in which case we know it's GR, somehow. - MLD

Hello Ben,
In order to test the current hypothesis, I upgraded my system from Ubuntu 16.04 to 18.04 and GNU Radio from 3.7.11 to
Still, the leak persists. Surprisingly, Michael didn't experience the issue on his MacOS, running the exact code I'm running at the moment. 
I'm not sure what could cause the issue in Ubuntu.
