[Pkg-directfb-devel] Bug#506666: libdirectfb-1.0-0: SDL apps crash in DirectFB on PPC

[Leslie Viljoen]

Package: libdirectfb-1.0-0
Version: 1.0.1-11
Severity: critical
Justification: breaks unrelated software


This bug already reported in Launchpad, but no ppc support there.

This problem's first symptom is that you are completely logged out of your X session as soon as you try to run something like Tuxpaint on PPC. I have seen it on Fedora, Debian Lenny and Intrepid. Etch.5 worked fine, probably because directfb was version 0.9.

I have stepped though Tuxpaint until an SDL init:

SDL_Init(1048625)
(Those flags are: SDL_INIT_VIDEO | SDL_INIT_TIMER | SDL_INIT_AUDO | SDL_INIT_NOPARACHUTE)

I then stepped through the SDL code until here:
DirectFB_CreateDevice (devindex=<value optimized out>) at ../../src/video/directfb/SDL_DirectFB_video.c:123

DirectFB_CreateDevice crashes. It sometimes prints the error below, but mostly
it doesn't print anything, it just terminates the session. Since it looks permissions related I have
run everything as root but that doesn't help.

The machine I am running is a G4 Mac Mini (powerpc).
The graphics card:

I have already gone through three distributions, rebuilt Tuxpaint and SDL from source
with debug symbols and stepped to discover the problem - so I'm willing to help
fix this.
