Description Flightbase 2006-08-24 08:21:19 UTC 
The problem seems to show up with devices, which have more then 4 axis. at least i have 2 different joysticks with 5 and 6 axis.
both are detected as /dev/input/js0 correctly. 

for example the "GREAT PLANES InterLink" joystick - it has 5 axis - and 5 buttons. sdl says: 

Opened Joystick 0
Name: GREAT PLANES InterLink
Number of Axes: 20
Number of Buttons: 5
Fatal signal: Segmentation Fault (SDL Parachute Deployed)

this happens for different programs, which are using sdl: crrcsim, slope soaring simulator.

is there any way to tell sdl that this joystick got only 5 axis? would this solve the problem?
for other games (x-plane) the joystick is working perfectly - so i think the support at all is given.

thanks for any help.

Is this still active in SDL 1.2.11?

No update in a few months, and it's regarding an old version of SDL, so I'm closing this for now.  If you retest and find it still active in the current SDL code (http://www.libsdl.org/tmp/SDL-1.2.tar.gz) please reopen this bug.

If you're not able to debug SDL and find out what's going on and want to loan me your joystick, that's fine, just let me know.
