Hi, I just ran an older script and the recent gretl version (Aug 5) told me (correctly) that I had used the same loop index in two nested loops. (Cf. the recent change that we discussed.)
So I adjusted the script and changed the nested loop index. Saved and re-ran, which made gretl crash. The same script runs fine after starting gretl again, so I cannot (easily) reproduce right now. thanks, sven
