scan-build bugs

[disconnect3d]

Hi,

I haven't investigated them, but there are 5 bugs that scan-build, a free static analysis tool, can detect in the parson code.

Running it is as simple as running those commands on Debian/Ubuntu:

$ sudo apt install clang-tools  # install scan-build
$ git clone https://github.com/kgabis/parson
$ scan-build make
$ scan-view …

Hope this helps.
