Re: [Gretl-devel] a short script to crash Gretl on xp: working modification
Dear Allin,
I haven't noticed any problems with armax()
on Ubuntu, Kubuntu, windows 7,
xp is the exception.
Also, I have tried like this:
write
arima 2 0 2; ....
inside the loop ond 0,0 parameters for loop
to be executed only once
the same: gretl crushed on xp
And no similar problems on other systems
Oleh
P.S.
I use armax() in my course twice:
autocorrelation in ols
and
time series (arima, X13, exponential smoothing, ets.)
I have about 150 students per year
Honestly, I'am sick and tired of answering bug
questions to students
I wrote a function to select best seasonal arma,
and something else about lags and plan
to package it soon

Let's see if you're right that arma 2 2 in a double-loop is the
active ingredient in the crash on XP. If so, then the following
minimal script should presumably crash too.
nulldata 100
setobs 1 1 --special-time-series
set seed 77431
series y = normal()
loop p=1..2 -q
loop q=1..2 -q
catch arma p q ; y -q
endloop
endloop
(Meanwhile I've tried running the armax package on Linux, using a
gretl build with gcc's full stack protection turned on, and I'm not
seeing any stack-smashing.)
