Symptoms:
	PHKL_25243:
	Partial port of 10.20 patch PHKL_22701.
	The process creates a core file even if the core file size
	is set to 0 by setrlimit(2) call.

	PHKL_20081:
	A program running at a sensitivity level higher than the
	sensitivity level of the process's current directory may
	not be able to dump core.

Defect Description:
	PHKL_25243:
	Partial port of 10.20 patch PHKL_22701.
	After setting a size of 0 by setrlimit(2) call, and aborting
	the process, the process creates a core file of size 0.
	Which should not have been created as per setrlimit(2)
	man page.

	Resolution:
	The check for size 0 has been added in the code, it won't
	create core file if the size is 0.

	PHKL_20081:
	Core dump handler could not write to directory in all cases.

	Resolution:
	During the core dump handler, raise the allowmacwrite
	privilege to ensure that the write succeeds.
