If I try to recompile a file that features an empty instrument I get a
problem. On the first run everything is fine, but as soon as I call
csoundReset() I get a crash. My instrument is simply:

instr 1
endin

Actually, hold on, it seems all my instruments are dying on
recompile...I'll keep back to you all when I figure out what exactly
it going on. :)

Ok, it turns out that if I recompile any orchestra with nchnls=1 I get
a problem with csoundReset(). I'm not sure it's a Csound problem.
Cabbage makes assumptions that all instruments are stereo. Still, by
the time csoundResst is being called I'm not accessing any audio
buffers, so I really can't think why it might crash. In the meantime
I'm going to make sure nchnls is 2 in my CSOUND_PARAMS structure.

What do you mean? I can recompile nchnls=1 no problems here. 
Are you changing from stereo to mono? You can only do that 
after reseting and starting Csound again.

No. I'm simply reloading the exact same instrument as before. The
configuration of the channels remains unchanged.

I do something along these lines in my processing loop:

for(int channel = 0; channel < getNumOutputChannels(); channel++ )
{
(...)
CSspin[channel+pos]


I make the assumption that Csound always has the same number of
channels as the plugin. But if I'm working in mono this will move the
index outside the CSPin buffer no?

If you can produce a small C program to debug it, because I can't reproduce it here.

Not really a goer as I'd need to implement my own audio callback IO
routines too. If it pops up again I'll let you know. Overriding nchnls
does the trick. I should have been doing that anyway.

That's what I was thinking. Only I don't see why I don't get them the
first time around. Anyhow, no need to worry about it.

Because there is a lot of memory being allocated and used, the effects of this might not be apparent sometimes (ie. might not
lead to a crash, because you're overwriting somewhere else that the program has allocated but not used yet), 
but if you were to run this in valgrind, the errors would show up.
