Re: [Chicken-users] Segfault with large data-structures

[Arthur Maciel]

Kristian, thanks for reporting that. 

I've been running through csi for aproxiamtely 10 hours and it never seems to finish. I'm not sure this task is that big.

I'm getting the same result here, when I run it through csc. When I run it through csi, though, it never seems to finish - is the task that big? I had to kill it after 2-3 hours.

address@hidden ~]$ csi -version

What version of chicken, and if 4.8.0 for example could you try 4.7?
