Background:
===========
* Trying to determine if a memory leak exists in trying to diagnose
https://github.com/abraunegg/onedrive/issues/893
* Valgrind is showing some interesting data re uninitialised values and
possibly lost blocks

Valgrind errors:
================
* Use of uninitialised value of size X
* Conditional jump or move depends on uninitialised value(s)
* Uninitialised value was created by a stack allocation

Files Attached:
===============
* main.d (reproducer)
* valgrind-out-202005101049.txt (valgrind output)
* make_with_dmd.sh (compile & test with valgrind)

Questions:
==========
Is this a valid bug? I have looked through json.d and to me, everything looks
like it gets initialised correctly.
