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

Message:
I installed the latest Winxound and was able to save the error output.
CsoundQt crashes immediately so i was unable to get the output.
The output is attached.
I'm on Xubuntu 12.04 64 bit

can't reproduce the crash in your second example either (setting nchnls=2)

Message:
Sorry I can't reproduce the crash here. I don't have four channels, but I
am using file output. Can you check if this crashes with file output too?

The opcode seemed to ber repaired but it is not.
Here is an example from John Ffitch:
; 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
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
i 1 0 10

a screenshot of the crash is attached
