My beloved gretl crashed on me. (: My scrip was doing great for that last year until I added a line with the coeffsum command. It repeatedly crashed over and over again. So I setup a small test dataset and invoked gretlcli, and it seems that coeffsum worked the first time, and crashed the 2nd time with an error message of "Abort trap: 6”. What did I do wrong? Here are the files that you might need to replicate the situation and help me out: 1. a test dataset, 2. the scrip that crashes gretlcli 3. the log from gretlcli 4. two crash reports when I did run gretl & gretlcli.
