[GRASSLIST:4413] Re: mode()

[Maciek Sieczka]

Hi All!

Still no any answer so let me bug you a little more. I was thinking of
putting a bug report on this issue but first of all I don't know how to
describe it because it's weird and secondly COULD ANYBODY CHECK IF YOU CAN
REPRODUCE THE ERROR so I could make sure if I'm not a separated case? It's
hard for me to believe that such a nasty bug would survive in r.mapcalc and
I'm ready to be convinced that it's all my fault somehow.

In a given region:

projection: 0 (x,y)
zone:       0
north:      100
south:      0
west:       0
east:       100
nsres:      1
ewres:      1
rows:       100
cols:       100

I'm having adventures like this:

GRASS:~ > r.mapcalc 'map_mod=mode(2)'
 100%

GRASS:~ > r.mapcalc 'map_mod=mode(2,2)'
 100%
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=mode(2,2,2)'
 100%

GRASS:~ > r.mapcalc 'map_mod=mode(2,2,2,2)'
 100%
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=mode(2,2,2,2,2)'
 100%

GRASS:~ > r.mapcalc 'map_mod=mode(2,2,2,2,2,2)'
 100%
mv: nie można wykonać stat na
`/home/gr/home/grorient/wewn/.tmp/localhost/1197.0': No such file or
directory
ERROR: closecell: can't move
/home/gr/home/grorient/wewn/.tmp/localhost/1197.0
to cell file /home/grassdata/orient/wewn/cell/map_mod

GRASS:~ > r.mapcalc 'map_mod=mode(2,2,2,2,2,2,2)'
 100%
mv: nie można wykonać stat na
`/home/grorient/worient/wewn/.tmp/localhost/1201.0': No such file or
directory
ERROR: closecell: can't move
/home/grorient/worient/wewn/.tmp/localhost/1201.0
to cell file /home/grassdata/orient/wewn/cell/map_mod

GRASS:~ > r.mapcalc 'map_mod=mode(2,2,2,2,2,2,2,2)'
 100%

where "mv: nie można wykonać stat na" means "mv: cannot execute stat on"

beautifull, isn't it?

or take a look at this:

GRASS:~ > r.mapcalc 'map_mod=mode(1,2,3,4)'
 100%

GRASS:~ > r.mapcalc 'map_mod=mode(1,2,3)'
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=mode(1,2)'
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=mode(1)'
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=median(1)'
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=median(1,2)'
Segmentation fault

or this one:

GRASS:~ > r.mapcalc 'map_mod=mode(5,5)'
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=mode(5,5,5)'
Segmentation fault

GRASS:~ > r.mapcalc 'map_mod=mode(5,5,5,5)'
 100%

GRASS:~ > r.mapcalc 'map_mod=mode(5,5,5,5,5)'
 100%

GRASS:~ > r.mapcalc 'map_mod=mode(5,5,5,5,5,5)'
 100%
Segmentation fault

These listings come from a cvs Grass 5.3 (grass53_exp_2004_08_21) built from
source on a Mandrake 9.2 but I've had this fun in a precompiled 5.03 too.

Looking forward to any reply.
