"""
Test lldb Python API object's default constructor and make sure it is invalid
after initial construction.

There are also some cases of boundary condition testings sprinkled throughout
the tests where None is passed to SB API which expects (const char *) in the
C++ API counterpart.  Passing None should not crash lldb!

There are three exceptions to the above general rules, though; API objects
SBCommadnReturnObject, SBStream, and SBSymbolContextList, are all valid objects
after default construction.
