segmentation fault when loading local file

[Pablo Rodríguez]

lightspark crashes when loading http://www.archive.org/download/Lessig-Free_Culture/lessig-freeculture.swf locally.

Here is the gdb output:

[Alessandro Pignotti (a-pignotti)]

Could you please try again with the current version? (0.3.5)

[Alessandro Pignotti (a-pignotti)]

Can you give some details about your hardware configuration? (CPU/Video card/Video driver/linux distribution)

[Didier Raboud (odyx)]

FYI it works here with 0.3.5

[Didier Raboud (odyx)]

(where "works" = "doesn't crash") :p

[Alessandro Pignotti (a-pignotti)]

Ok, I think that bug #582825 may be related to this, please report there any issues with a similar backtrace

[Pablo Rodríguez (ousia)]

Video card seems to be an ATI Technologies Inc Radeon Mobility X1400 (from lspci).

Ubuntu 10.04 seems to install the radeon drivers.

CPU is a dual core Intel T2050 @ 1.6GHz.

I hope this is complete.

Thanks,

Pablo

Just in case it might help, I attach the output from glewinfo.

[Pablo Rodríguez (ousia)]

Thanks, Alessandro, right now lightspark displays a message warning that the video card doesn't support OpenGL 2.0.

I have been googling for it and I guess this might be a lack in the implementation of the opensource radeon driver. At least this is what I understand from http://www.amd.com/us/products/notebook/graphics/ati-mobility-hd-x1000/x1400/Pages/x1400-specs.aspx.

Would you be so kind to confirm this?

Thanks,

Pablo

[Alessandro Pignotti (a-pignotti)]

Hi Pablo, could you please try the latest release? I'm allowing a more relaxed detection of features by glew now.

[Pablo Rodríguez (ousia)]

Many thanks, Alessandro. I get the standard "Aborted" message after a bunch of unimplemented features.

So, it is fixed now. Thanks again.

Just in case it might help, here you have the unimplemented features list contained in the log:
