Dear all, I've attached a json-file and ran the following example using latest git on ubuntu 18.10. Gretl crashes at some point when trying to access some element of a nested bundle as you will see. <hansl> string wd = "/home/at/git/json_gretl" # adjust path string jfile = &quot;(a)wd/ex3.json&quot; string json_str = readfile(jfile) B = jsongetb(json_str, "/store/*" ) # all things in store eval B.store.book[1] # grab 1st of the 4 bundles # Accessing "price" of the 1st bundle works eval B.store.book[1].price # CRASH when accessing the 1st element (price) eval B.store.book[1][1] # Is this actually a valid accessor? </hansl> Best, Artur
