Symptoms:
	PHCO_31246:
	( SR:8606369189 CR:JAGaf29733 )
	sed (1) dumps core if the hold space required increases
	beyond 4096 bytes.

Defect Description:
	PHCO_31246:
	( SR:8606369189 CR:JAGaf29733 )
	When the hold space of sed(1) grows beyond 4096 bytes
	one of the pointers to this buffer gets dereferenced
	resulting in further writes to hold space corrupting
	the heap and causing sed(1) to coredump.

	The defect can be reproduced with the following steps:
	1. Create a 'testfile' which has size greater than
	   4k. For example, use the following script:

	   I=0
	   while [[ $I -lt 100 ]]
	   do
	        echo "This is line $I, and this is to make the \
	line a bit longer"
	        I=$(($I+1))
	   done > testfile

	2. Use sed(1) on the testfile and reverse the lines
	   as follows:
	   $ sed -n -e '2,$ G' -e '1,$ h' -e '$ g' -e '$ p' testfile
	   Memory fault(coredump)
	In step 2, sed(1) core dumps when sed(1) should have
	continued to reverse the lines.

	Resolution:
	Now sed(1) has been modified in such a way that it can
	handle hold space greater than 4096 bytes.

Enhancement:
	No
