	  This option is to be used when the saving of IPA register state is

	  desired upon a fatal system exception. When an exception occurs,

	  an IPA register collection algorithm will be run in the context of

	  the exception handler.  A predefined set of registers will be read

	  and their values will be placed into a static hierarchical data

	  structure that can be perused post crash.
