I'm just about ready to put out gretl 1.8.2, but there's one
outstanding item of business.  Ignacio reported to me that he was
getting a crash from the following script:

<script>
nulldata 115
matrix trendm=t-1
</script>

I've tried at some length but I'm not able to replicate the
problem.  I'm not saying the problem doesn't exist.  Ignacio gave
me a different hard-to-replicate problem not so long ago and
eventually I found a definite, if elusive, bug.

I'm assuming that the problem ocurred while using the GUI program
in Spanish.  In my attempts at replication I've used both gretlcli
and gretl_x11, in both English and Spanish.

Can anyone else replicate the crash?  If so, could you please try
it under gdb and/or valgrind (with gretl compiled with debugging
symbols) and send me the trace?

Thanks very much,

Allin.

Totally off-topic, but I just wanted to say that I'd rather use the seq() 
function for that. Sorry!

The problem seems to be solved now.

I do not know why when I have done several "cvs update"s gretl begins to work 
badly. Now I uninstalled gretl completely and downloaded it enterely from the 
cvs and gretl is not producing the segmentation fault.

Umm... ok, now I will use 'matrix trendm=seq(0,n)' 
but I had to look for seq() in the gretl manual and 'trendm=t-1'  was so 
intuitive... ;-))

no crash here either, with current cvs.

(I almost sent an email with "now" instead of "no", if that got through
to you, please ignore that)

OK, thanks.

Maybe you're doing this already, but When building gretl from CVS
I'd recommend the following routine:

cvs update -P -d
CFLAGS='-g -O2 -Wall -W -Wno-unused-parameter -Wno-sign-compare' \
  ./configure <options>
make clean
make 2>errors
[ inspect the "errors" file ]
[ sudo ] make install

In the cvs command, -P removes local copies of files that have
been deleted in CVS, and -d ensures that if a new directory has
been added, you get a copy of that.

The CFLAGS setting on the configure line sets warnings to the max
("-Wall -W"), other than a couple of things which will produce
very verbose and not very useful output (i.e. "-Wno-foo"
suppresses warnings with regard to foo in particular).

The "make clean" step is not generally required, but I tend to do
this if I see any odd behavior from gretl.

Allin.
