[Gretl-devel] Re: "empty" return value

Load the attached script marrtest.inp (in the GUI program) 3. Run it the 1st time; for me this prints out "yay" without error. 4. Run it another time, then I get a "data not conformable" error It's weird because the error only appears in the second run -- but it's reproducible here on Windows with a recent post-2026a snapshot. Note when I replace the line "return defarray()" with a more explicit two-liner: matrices M = empty return M then things seem to be more robust, so I suspect it's related to the fact that defarray() alone doesn't convey sub-type information. OTOH, using array(0) instead also works. thanks sven
