VLC player (both 0.8.6 and 0.9.0) both play audio CDs flawless until the end of the CD is reached. Instead of stopping playbak, the player reports a seqfault, quits and dmesg shows:vlc[19719]: segfault at 4646496a eip b726dc88 esp b03ff0f0 error 4.I tried with various CDs on two different installations of Gentoo Trying compiling with different versions of libcdio does not resolve the problem. Disabling cdda and cdio in the USE flags, however, does. CDs play normal and player does not crash at the end of CDs Reproducible: Always Steps to Reproduce: 1.compile with use="cdda cdio" 2.play audio CD 3. Actual Results: Player crashes with a segfault and the a/m message in dmesg Expected Results: Player should finish playing the CD gracefully and go into standby mode Used the use flags recommended on the VLC web site and compiled both on an intel pentium-m and an intel t2080 with the following c-flags: -Os -march=i686 -pipe
if you can reproduce it with vlc-0.9.0_alpha20080625, could you please try to give me a nice backtrace ? http://www.gentoo.org/proj/en/qa/backtraces.xml

(In reply to comment #3) > I would, but emerging that version fails: Yep, should be fixed now, sorry for that. I enabled swscaler plugin with ffmpeg bug forgot to bump the dep... shame :/
Ok, I tried to emerge the latest vlc again and it worked. It does not want to play my audio Cd anymore, nor mp3s for that matter. It displays some cddb information and then just hangs. I don't feel like working with the unstable version anymore. VLC is the only unstable package I had on my system and I am downgrading it again. Not worth the trouble. Again, there is a problem with cdio and the stable release as well. If you want me to run a backtrace there and send it to you, I can do that, but I don't want to mess with the unstable package anymore.

Thanks for the bt; is your cd 99 tracks long or is that a bug somewhere else ? if it is 99 tracks long, could you please try with a cd with less tracks ? and if it doesn't fail anymore, could you please try opening a ticket on https://trac.videolan.org/vlc telling it fails with 99 tracks CD as that is probably a +1 missing from an allocation and I don't think I have a 99 tracks cd here :/
Actually,the CD I was playing has only 2 tracks and vlc segfaults at the end of track 2. It does not matter, what CD I am using, the player always crashes at the end of the last track.
could you please try with 1.0.5 ? I've lost track of this bug and it may have been fixed
