When I've tried to generate 'fcast --out-of-sample

based on arima model I got crash and following GDB results:

Note, that it happens whene I generate forecasts inside the function
package. In normal script it works fine:
---
open bjg
smpl 1949:01 1959:12
arima 0 1 1 ; 0 1 1 ; lg --quiet
fcast --out-of-sample --no-stats

Can you give some more context, please? I tried the following:
<hansl>
function void fcbug (series y)
arima 0 1 1 ; 0 1 1 ; y --quiet
fcast --out-of-sample --no-stats
end function
open bjg
smpl 1949:01 1959:12
fcbug(lg)
</hansl>
This runs OK and gets a clean bill of health from valgrind.
I also tried moving the smpl command inside the function;
still no problem. So it seems we need more background to
replicate the bug.
