If you're using linux, you might try "ulimit" in the terminal type ulimit -a to see all the things you can configure ulimit -s 20480 sets the stack size to 20 Mb, it is by default 10 Mb I don't know if this will work... I don't profess to understand threads or stacks, and pd might have its own system for setting max stack size. I have had a recursive problem once that was solved using ulimit. Chuck Henry

I don't understand. I've understood recursive to mean a function that calls itself within itself. The output from my patch retriggers the patch, but to my understanding it should all be determinate; if Pd uses depth-first message passing, it should finish with one thread before calling the next. The abstraction is only retriggered from its left outlet, so nothing should happen during the 10 ms delay.
I'm also not sure how [until] will help. Pd doesn't know how many scalars the score has, or how many are of any one structure.
I'm still not clear on what "the stack" is or what makes it overflow. Thanks.

Can anyone explain more about what exactly "stack overflow" is? Might it help if I just put a 1 ms delay for each scalar?
you've written a recursive patch, so each recursion increases the interpreter stack ... if your recursions are happening too often ... booooooom ... :-/
it's probably better to solve something like this with an iteration, which doesn't use the stack ... in pd it can be done with the |until| object ...
