Path Name: /hp-ux_patches/s700_800/10.X/PHCO_23918

Symptoms:
	PHCO_23918:
	1. printf(1) dumps core if argument length is n*8-1

	2. printf(1) does not support multibyte characters as input

	3. printf(1) gives corrupted output when the argument
	   is long.

Defect Description:
	PHCO_23918:
	1. printf(1) dumps core if argument length is n*8-1 as one
	   extra null character has been put for which there is no
	   memory allocated.
	Resolution:
	   Extra null character insertion has been removed to avoid
	   the problem.

	2. printf(1) does not support multibyte characters as input
	Resolution:
	   Code has been changed to use wide characters which can
	   handle both multibyte and singlebyte characters in input.

	3. printf(1) was corrupting the output when
	   the argument length is more than LINE_MAX value.
	   This is because of the static allocation of
	   memory of size LINE_MAX.
	Resolution:
	   The fix is to allocate the memory dynamically
	   based on the argument length.
