Package: geomview
Version: 1.9.4-1
Severity: normal
Hi!
I noticed a problem with the PostScript snapshot saving option.
The option seems to work in some cases, but causes geomview to
segfault in other cases.
First test:
* start geomview with the following command:
$ geomview tref.off
* select Save [>] from the File menu
* in the Save dialog window, select "PostScript snapshot" and enter
"test_ok.eps" as Selection
* click on the OK button
* select Exit [Q] from the File menu
* check the resulting Encapsulated PostScript file
$ ls --size --si test_ok.eps
33k test_ok.eps
$ gv test_ok.eps
OK, it seems to work perfectly.
Let's proceed with the second test:
* prepare the following command file:
$ cat minimalist.gcl
(new-geometry "[g1]"
{
appearance { +edge -face }
LIST
{
MESH 2 3
1.1 1.1 0.0
2.2 1.1 0.0
1.1 2.8 0.0
2.3 2.9 0.0
1.1 3.4 0.0
2.3 3.5 0.0
}
{
MESH 2 3
3.1 1.1 0.0
4.2 1.1 0.0
3.1 2.8 0.0
4.3 2.9 0.0
3.1 3.4 0.0
4.3 3.5 0.0
}
}
)
(bbox-draw "[g1]" off)
(name-object "[g1]" "minimalist")
(backcolor "Camera" 1.0 1.0 1.0)
(ui-target "World")
(event-mode "[t] Translate")
* start geomview with the following command:
$ geomview minimalist.gcl
* select Save [>] from the File menu
* in the Save dialog window, select "PostScript snapshot" and enter
"test_fail.eps" as Selection
* click on the OK button
* the output on the terminal is:
Geomview(8397): internal error: "Segmentation violation"; dump core now
(y/n) [n] ?
* hit [Enter] on the keyboard and watch geomview exit
* check the resulting Encapsulated PostScript file
$ ls --size --si test_fail.eps
0 test_fail.eps
Nothing was produced!
What's wrong?
I experienced this problem on different boxes, with different video
cards. On all of them many GL applications work:
$ glxinfo | grep rendering
direct rendering: Yes
