@Dan
As far as I recall, going between abstraction to parent patch via
inlet~/outlet~ introduces a block delay, hence no error
There's no delay (as long as the blocksizes match).
@William
Second abstraction contains an effect in the feedback path. (in my
simple example, it's just a null wire: In-L passes to Out-L, etc).
Again this *works*, no DSP error.
But you're using [r~] and [s~] which is not the same as direct signal
connections. The former can act like a short delay line. Please read
"3.audio.examples/G05.execution.order".

Third patch is like the second, only the effect has been moved out of
the abstraction, and into the parent patch. ONLY HERE do I get the
DSP loop error.
Signal loop in a single patch without abstractions = error. Pd has no
way to read and write to the same signal buffer in the patch at the
same time *without* some tiny delay.

At the lower level, they don't. What happens if you put part of the
path inside a subpath which uses inlet~/outlet~?

It really seems like a bug to me.
I'll upload a test patch a little later.
Thanks,
