[Gretl-devel] 32 bit-64 bit compatibility

During the time elapsed I have got some more clues. In my program, I am
using the arma estimations. And this problem occurs in the case when my
dependent variable is constant for a long time. When I investigate my log
file it says:

Kalman bla bla returned 36

Deleting var 8 (x1) at list pos 8: all zero

The weird thing is I am handling this situation (If arma returns some
 number other than 0, i am making persistent estimation). When I look at
the results, it seems that it is handled. However, When I look at the task

manager, It seems that Gretl is still working and consuming 98% of CPU. As
I said before, This situation was not present on 32 bit Ubuntu.

I am very thankful for your helps.
