--- Comment #2 from Phil Muldoon <pmuldoon at redhat dot com> ---
gdb.Architecture should never be instantiated directly.  Regardless, we should
gate the calls to the functions to check that there is a valid architecture.  I
have a patch pending for this.  I will update the PR when it is submitted,
reviewed and accepted.

Just as a note, to get an architecture object, one should obtain it from a
frame.  
For example:

frame = gdb.selected_frame()
arch = frame.architecture()

As each frame can have a different architecture.
