Summary: outrg issue

Initial Comment:
outrg does give the right results, but closes more than once with a memory invalid pointer error

example:
<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac    ;;;realtime audio out
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o outrg.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 44100
ksmps = 32
nchnls = 4	;quad
0dbfs  = 1

instr 1

kcps = p4
asig1  vco2 .5, 55						;sawtooth1
asig2  vco2 .5, 110						;sawtooth2
asig3  vco2 .5, 220						;sawtooth3
asig4  vco2 .5, 440						;sawtooth4
kstart randomh 1,4.99, kcps					;choose between 1 and 4
kstart = int(kstart)
printks "number of the first channel = %d\n",1/ p4+0.1, kstart	;decide what will be the start channel for asig1
      outrg kstart, asig1, asig2, asig3, asig4			;start with 55 Hz in channel1, 110 Hz in ch.2,  	
								;220 Hz in ch.3, 440 Hz in ch.4
endin
</CsInstruments>

Message:
The opcode seemed to ber repaired but it is not.
Here is an example from John Ffitch:

<CsoundSynthesizer>
<CsOptions>
; Select audio/midi flags here according to platform
-odac    ;;;realtime audio out
;-iadc    ;;;uncomment -iadc if realtime audio input is needed too
; For Non-realtime ouput leave only the line below:
; -o outrg.wav -W ;;; for file output any platform
</CsOptions>
<CsInstruments>

sr = 48000
ksmps = 32
nchnls = 4        ;quad
0dbfs  = 1

instr 1

kleft init 1
asig  vco2 .5, 220			;sawtooth
idur = p3/(nchnls-1)
knext init idur
kpos init 0
krate init 1/idur
kbase init 0
ktime timeinsts
if ktime>=knext then
  kleft = kleft + 1
  knext = knext + idur
  kpos = 0
  kbase = ktime
else
  kpos = (ktime-kbase)/idur
endif
;printks "speaker %d position %f\n", 0, kleft, kpos
a1,a2 pan2 asig, kpos
      outrg  kleft, a1, a2
kpos = kbase/idur
endin

</CsInstruments>
