Bugzilla Bug 135101

Blender causes a segfault at startup. I tested 3 versions of Blender and
experienced a segfault shortly after it prints the Python version string.
Versions tested were an old one I had laying around (2.36), current version
from portage (2.41), as well as a fresh CVS checkout.

I finally narrowed it down to SDL 1.2.10, reverting to version 1.2.9
immediately  made the segfault go away and now everything works perfectly.

The same segfault problem was encountered on two systems, the segfault problem
was resolved by reverting to SDL 1.2.9 in both cases. Both systems were using
ATI Radeon 9800 graphics cards, using the closed-source ati-drivers installed
from portage, it wouldn't surprise me if that had something to do with the
problem.

Same segfault here (nvidia driver), evoked at:
intern/ghost/intern/GHOST_SystemX11.cpp:107 --> m_display = XOpenDisplay(NULL);

After reemerge all dependecies

media-libs/freetype-2.1.10
media-libs/libpng-1.2.8-r1
media-libs/jpeg-6b-r7
media-libs/openal-20050504-r2
media-libs/libsdl-1.2.10 !!!

blender works again :-)

+ media-libs/ftgl-2.1.2-r1

looks like http://bugzilla.libsdl.org/show_bug.cgi?id=242

Simply re-emerging all the depencies doesn't work here (at least not only those
previously mentioned).
With ati-drivers and amd64.

As mentionned on bugs marqued dupliquate of this one, this version of sdl
produce segfault with other apps than blender (like links on my system).
reverting to 1.2.9 fixes. Emerging all depedencies (emerge -e blender) didnt
work here.

Regards

Charly

Other affected apps which are affected by this bug:

- BitTornado (GUI version only, should be the same issue with python as the
Blender problem)
- VLC
- GNU gnash

It seems almost every dynamically linked SDL app segfaults when using
libsdl-1.2.10.

Please add "e-uae" and "avidemux" to the list of affected apps.

I think bug 136291 and 136353 are dupes of this.

USE=-sdl emerge ... made both avidemux2 and e-uae work again for me. e-uae gets
past the first segfault (it fails later, but that may due to the fact that I
don't have any data to use it with).

Please add "ekiga" and "audacity", also affected by the segfault. When I
downgrade libsdl (1.2.9-r1 instead of 1.2.10), the segfault disappears.

Also amule, see bug 135250

revdep-rebuild should fix the issue.

(In reply to comment #12)
> revdep-rebuild should fix the issue.

Please read the bug - this is a fault caused by libsdl-1.2.10, not by apps
being linked to the wrong version.  Rebuilding all the deps makes no
difference.

see http://bugzilla.libsdl.org/show_bug.cgi?id=242

"ugh, the OpenGL library is resolving the X11 symbols from the SDL library,
instead of from the X11 library.  When SDL unloads the X11 library, those
symbols are no longer available."

That seem to be also the bug here - previously I saw in the debuger 
that sdl was somehow hijacking the symbol for the XOpenDisplay(NULL)
blender's call to libX11.so and instead going thru null pointer
witch certainly segfaults.

How ever, now the bug mysteriously disappeared and I _have_
(see Comment #3) latest nvidia's opengl and for the unbelievers: ;-)

equery b /usr/lib/libSDL-1.2.so.0.7.3
[ Searching for file(s) /usr/lib/libSDL-1.2.so.0.7.3 in *... ]
media-libs/libsdl-1.2.10 (/usr/lib/libSDL-1.2.so.0.7.3)

and realy, audacity or blender runs without any problems ...

I reverted back to 1.2.9-r1 and Blender is happy again. From what I understand
from the SDL bug report, they're tweaking things to get it to work, so
hopefully 1.2.10-r1 will have a solution integrated in... 
gcc 3.4, i915 driver on modular X with a fresh install of Gentoo.

1.2.11 now in portage
