Path Name: /hp-ux_patches/s700_800/10.X/PHCO_21087

Symptoms:
	PHCO_21087:
	   When a diff file of zero lines of context is
	   applied to a file, patch(1) dumps core with
	   an "Assertion failed" error. When the reverse
	   diff of zero lines of context is applied to a
	   file, patch command reports "Unexpected end
	   of hunk" error.

	PHCO_16399:
	patch(1) dumps core with the message -
	1. "Assertion failed: fillsrc==p_end+1 ||
		fillsrc==repl_beginning, file pch.c,
		line 644" when a context diff file is
		applied to it.

Defect Description:
	PHCO_21087:
	   The diff file of zero lines of context is not
	   interpreted correctly because of the missing
	   conditions. This particular case was not
	   considered in the previous patch. So, the
	   errors are reported in case of patching a file
	   with zero lines of context diff.

	   Resolution:
	   More conditions are added to make sure that the
	   diff file of zero lines of context is interpreted
	   correctly and patching is done appropriately.

	PHCO_16399:
	patch(1) dumps core when a context
	diff file is applied to the command
	due to the incorrect handling of fillsrc
	count.
