<pre>As reported in <a href="https://github.com/Tencent/rapidjson/issues/1651">https://github.com/Tencent/rapidjson/issues/1651</a> the clang
Static Analyzer reports an issue in a very simple, two lines, RapidJSON
program.
AFAICT when it does "allocators.h:205:13: note: Assuming 'originalPtr' is not
equal to null" it's making an error (fails to see a constrain). If chunkHead_
is NULL, then originalPtr must also have been NULL.</pre>
