In _cbson_bson_to_dict and _cbson_decode_all we declare a Py_buffer like this:

Py_buffer view;

Coverity complains about this with: "var_decl: Declaring variable view without initializer."

This is not a bug because we always initialize the buffer with PyObject_GetBuffer before attempting to use it however it still could be a good idea to initialize it to 0, like this:

Py_buffer view = {0};

This change could help remove these false positives in Coverity.
