Summary: Memory leak in subroutine call when using paramters

Initial Comment:
Subroutine calls that pass parameters cause a memory leak in TExecuter_htp.exe and the Script Modeler.  This is severe enough in some cases that we have to manually set variables instead of using parameters in a subroutine call to pass data into a subroutine.

I'm running OpenSTA 1.4.3.20 on Windows XP Pro SP2.  Sample code that quickly demonstrates the leak when running under a single VU is below.

---------------------
!Browser:IE6
!Date : 4/20/2006
Environment
	Description ""
	Mode		HTTP
	Wait		UNIT MILLISECONDS

Definitions
	integer loop
	character*8192 foo
	
Code
	do loop = 1, 2, 0
		do loop = 1, 1000
			call makeleak ["aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"]
		enddo
		wait 1
	enddo

subroutine makeleak [foo]
end subroutine
---------------------

Warning: the Script Modeler tends to become unresponsive when running this script.
