Harmful is probably a strong word as you suggest. Problematic may be a
better word to describe it. Beyond the ability of reusing this "lost"
memory after the application closes, the main issue is that test cases
for memory leak will fail (I regard success as no memory leak reported
by _CrtDumpMemoryLeaks()) because of this insignificant memory leak.
That is the main reason I am looking for a function that frees this
