This should be now fixed in git.

Good, I tend to think it's a pretty severe bug, for example for teaching
purposes...

[I'm moving this to gretl-devel because it's fairly technical, but IMO
wotrh reading for people who like to see what's going on in the C sources]
In fact, it was pretty subtle: the C construct that was causing trouble
was
na(x[j++])
and you would think: "OK, this evaluates if x[j] is missing, and then
moves on"; not quite. In fact, na(x) has become (after the big NADBL
reoganisation) a macro in which TWO calls are performed, so j would go
straight from 0 to 2. I performed a search for similar construct in the
whole source tree and fortunately there seem to be no more instances.
