Browse Source 
* Possible fix for #4485

Throw's an exception when i is nullptr,
also added a testcase for this scenario though most likely in the wrong test file.cpp

* quick cleanup

* Fix compile issues

* moved tests around, changed exceptions, removed a possibly unneeded include

* add back include <memory> for testing something

* Ninja doesn't like not having a \n, at end of file, adding it back

* update input_adapter file to deal with empty/null file ptr.

* ran make pretty

* added test for inputadapter

* ran make amalgamate

* Update tests/src/unit-deserialization.cpp
