SAPF: weird error message

Sometimes I get this error message when I run my sapf code:

Failed to load cookie file from cookie: Too many open files

On persisting to interact with the interpeter, it throws a segmentation fault. In this code I don’t open any files at all, nor do I interact with any ‘cookies’, so I must assume that this is going on ‘under the hood’. All I can think of is I do use the Y function, maybe wrongly.

I use a ThinkPad:

/var/git/sapf$ cat /etc/os-release

Does anyone make sense of the problem I’m having?
