Symptoms:
	PHSS_31086:
	JAGaf26050: Unwind express library did not properly
	  unwind from routines with a large number of spilled
	  registers.

	PHSS_30232:
	JAGae66019: Unwind library was not able to process
	  exceptions thrown under low-memory conditions.

	PHSS_30017:
	JAGae93989: Unwind library previously did not support
	  exceptions thrown from a signal handler; the application
	  would have been aborted when an thrown exception was
	  not caught before unwinding into a signal handler frame.

Defect Description:
	PHSS_31086:
	JAGaf26050: Unwind express library did not properly
	  decode priunat_when descriptor.

	PHSS_30232:
	JAGae66019: The unwind library needs to be able
	  to allocate memory in order to unwind, but in
	  low-memory conditions, it could not obtain the
	  necessary memory.

	PHSS_30017:
	JAGae93989: The C++ standard explicitly disallows
	  throwing exceptions from a signal handler, so the
	  runtime support was not designed to support it.

Enhancement:
	No (superseded patches contained enhancements)
	PHSS_30017:
	JAGae93989: This patch delivers new support for
	  exceptions thrown from a signal handler.
