We have made good progress at identifying and correcting the heap leaks in our application.
Additional tools were used in order to accomplish this, i.e., compile
with CLANG, and use asan.

The U++ snapshot that we are now using is upp-x11-src-9004.tar.gz

We are left with two heap leaks that we have yet to resolve.
Memory breakpoint 22748 is in our own application and we take ownership of that issue.

However, memory breakpoint 22235 is a real puzzle because it is almost exclusively is in U++ library.
Here is the log-file followed by a snapshot of the debugger call-stack:
