Hi,

I have installed gretl (from git) in a new PC (Ubuntu Linux 22.04), and I have installed X13 from the link in main gretl webpage: https://sourceforge.net/projects/gretl/files/x13as/x13as-linux-64.tar.gz

When I try to use it with some seasonal series, for example reskwh in data9-3.gdt, I obtain an error:

Line 22: arima {model=(72 133 192)(15 132 213) ^ERROR: Maximum number of MA lags, 72 exceeded.
