Hi everyone,
I had recently an issue with both pil64 and pil21. I was trying to create a
large circular list and got a segmentation fault with a size of >200'000
elements. Is that expected?
(apply circ (range 1 20))
Regards,
Davide
Just found out that it is an issue with apply. Probably the number of
arguments is too large.
(eval (cons 'circ (range 1 20)))
Works fine.
Could someone confirm please?
Regards
Davide

.. but of course the fix is trivial :)
: (cdr (let L NIL (for I 7 (fifo 'L I)) L))
-> (1 2 3 4 5 6 7 .)

Thanks for the clarification Alex! The ulimit command did the trick.
Cheers,

Yes, this is a known issue. It is a stack overflow.
'apply' builds structures on the stack.
The recommended way is to set
ulimit -s

Building a long list with 'range' just to apply it (e.g. to 'circ') is rather
inefficient.
In this case, I would recommend 'fifo' to
